DATA SHEET
BIPOLAR ANALOG INTEGRATED CIRCUIT
PC3018, 3025
LOW-SATURATION STABILIZED POWER SUPPLY WITH ON/OFF FUNCTION (1 A OUTPUT)
DESCRIPTION
The PC3018 and 3025 are low-saturation type regulators with an output current of 1 A at respective output voltages of 1.8 and 2.5 V. These regulators are also provided with an ON/OFF function, which reduces the dissipation when there is no load, making them ideal for systems requiring low power consumption.
FEATURES
* ON/OFF pin for output control (active-high) * Output current capacitance: 1 A * Low minimum voltage difference between input and output (VDIF = 0.5 V MAX. (when IO = 0.5 A)) * Output voltage accuracy: 2% * On-chip inrush current protection circuit for when input voltage rises (when input voltage is low) * On-chip overcurrent limiter and thermal shutdown circuit * On-chip safe operating area controller

Note The total dissipation is limited by an internal circuit. Where TJ > 150C, an internal protection circuit cuts off the output. Caution Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any parameter. That is, the absolute maximum ratings are rated values at which the product is on the verge of suffering physical damage, and therefore the product must be used under conditions that ensure that the absolute maximum ratings are not exceeded.
TYPICAL CONNECTION

INPUT CIN
PC3018, PC3025 + COUT
OUTPUT D2
Must be 0.1 F or more. Determine the capacitance in accordance with the line between the power supply smoothing circuit and input pin. Be sure to connect this capacitor to prevent abnormal oscillation. Use of a capacitor with excellent voltage and temperature characteristics, such as a film capacitor, is recommended. Note that some laminated ceramic capacitors have poor temperature and voltage characteristics. When using a laminated ceramic capacitor, the capacitance of 0.1 F or more must be reserved in the voltage and temperature ranges used. COUT: Must be 10 F or more. Be sure to connect this capacitor to prevent oscillation and to improve transient load stability. Connect CIN and COUT as close to the IC pins as possible (within 1 to 2 cm). Also, when using the device at 0C or less, use an electrolytic capacitor with low impedance characteristics. D1: Connect a diode if the voltage on the OUTPUT pin is higher than that on the INPUT pin. D2: Connect a Schottky barrier diode if the voltage on the OUTPUT pin is lower than that on the GND pin. CIN: Caution Ensure that voltage is not applied to the OUTPUT pin externally. Supply VIN and VON/OFF from different power supplies. Design so that VIN and VON/OFF either rise at the same time or VON/OFF rises after VIN.

Caution
The recommended operating range may be exceeded without causing any problems provided the absolute maximum ratings are not exceeded. However, if the device is operated in a way that exceeds the recommended operating conditions, the margin between the actual conditions of use and the absolute maximum ratings is small, and therefore thorough evaluation is necessary. The recommended operating conditions do not imply that the device can be used with all values at their maximum values.

PC3018, 3025
CAUTION ON USE
If the PC3018 and PC3025 Series are used with an input voltage that is lower than the recommended operating conditions, a large circuit current flows because the transistor in the output stage is saturated. The specification of this characteristic is the circuit operating current at startup, IBIAS
(S).
In this product, the circuit
current flowing at startup is limited by an on-chip inrush current protection circuit, but a circuit current of up to 80 mA may still flow. The power supply on the input side must therefore have sufficient capacitance to handle this circuit current at startup.
