LD2985Axx LD2985Bxx
Very low drop and low noise voltage regulator low ESR capacitors compatible, with inhibit function
Features

Very low dropout voltage (280 mV at 150 mA and 7 mV at 1 mA load) Very low quiescent current (2 mA typ. at 150 mA load and 80 A at no load) Output current up to 150 mA Logic controlled electronic shutdown Output voltage of 1.8, 2.5, 2.7, 2.8, 3, 3.3, 5 V Internal current and thermal limit Available in 1 % tolerance (at 25 C, A version) Low output noise voltage 30 mVrms Smallest package SOT23-5L Temperature range: -40C to 125 C means that when the device is used as local regulator, it is possible to put a part of the board in standby, decreasing the total power consumption. An external capacitor, CBYP = 10 nF, connected between bypass pin and GND reduce the noise to 30 Vrms. Typical application are in cellular phone, palmtop laptop computer, personal digital assistant (PDA), personal stereo, camcorder and camera.
SOT23-5L
Description
The LD2985A/Bxx is a 150 mA fixed output voltage regulator. The ultra low drop voltage and the low quiescent current make them particularly suitable for low noise, low power applications, and in battery powered systems. In sleep mode quiescent current is less than 1 A when INHIBIT pin is pulled low. Shutdown logic control function is available on pin 3 (TTL compatible). This Table 1. Device summary

Application notes
External capacitors
Like any low-dropout regulator, the LD2985 requires external capacitors for regulator stability. This capacitor must be selected to meet the requirements of minimum capacitance and equivalent series resistance. We suggest to solder input and output capacitors as close as possible to the relative pins.
6.2
Input capacitor
An input capacitor whose value is 1 F is required with the LD2985 (amount of capacitance can be increased without limit). This capacitor must be located a distance of not more than 0.5" from the input pin of the device and returned to a clean analog ground. Any good quality ceramic, tantalum or film capacitors can be used for this capacitor.
6.3
Output capacitor
The LD2985 is designed specifically to work with ceramic output capacitors. It may also be possible to use Tantalum capacitors, but these are not as attractive for reasons of size and cost. By the way, the output capacitor must meet both the requirement for minimum amount of capacitance and ESR (equivalent series resistance) value. Due to the different loop gain, the stability improves for higher output versions and so the suggested minimum output capacitor value, if low ESR ceramic type is used, is 1 F for output voltages equal or major than 3.8 V, 2.2 F for VO going from 1.8 to 3.3 V, and 3.3 F for the other versions. However, if an output capacitor lower than the suggested one is used, it's possible to make stable the regulator adding a resistor in series to the capacitor.
6.4
Important
The output capacitor must maintain its ESR in the stable region over the full operating temperature to assure stability. Also, capacitor tolerance and variation with temperature must be considered to assure the minimum amount of capacitance is provided at all times. This capacitor should be located not more than 0.5" from the output pin of the device and returned to a clean analog ground.
6.5
Inhibit input operation
The inhibit pin can be used to turn OFF the regulator when pulled low, so drastically reducing the current consumption down to less than 1 A. When the inhibit feature is not used, this pin must be tied to VI to keep the regulator output ON at all times. To assure proper operation, the signal source used to drive the inhibit pin must be able to swing above and below the specified thresholds listed in the electrical characteristics section under VIH VIL. Any slew rate can be used to drive the inhibit.

Application notes
6.6
Reverse current
The power transistor used in the LD2985 has not an inherent diode connected between the regulator input and output. If the output is forced above the input, no current will flow from the output to the input across the series pass transistor. When a VREV voltage is applied on the output, the reverse current measured flows to the GND across the two feedback resistors. This current typical value is 160 A. R1 and R2 resistors are implanted type; typical values are, respectively, 42.6 k and 51.150 k.
