| Micropower SOT-23, 120mA Low-Dropout Voltage Regulator ON/OFF Switch CLM2805 FEATURES DESCRIPTION CORPORATION * * * * * * * * * * * * * * * * * Smallest Possible Size (SOT-23-5) 5V, 4.8V, 4.5V, 4V, 3.5V, 3.3V, 3V, 2.5V Fixed Output Guaranteed Output Current in Excess of 120mA Available in Adjustable Output With ON/OFF Switch Internal Thermal Overload Protection Voltage Dropout is Less Than 100Mv at 50mA Output Reverse Battery Protection Short Circuit Protection Low Cost Solution The CLM2805 is a low power voltage regulator. This product is designed for battery-powered applications such as cordless telephones, radio control systems and portable computers. The CLM2805 features very low quiescent current (0.4mA) and very low dropout put voltage (typ. 50mV at a light load of 300mV at 100mA). Other features include the logic-compatible on/off input which enables the regulator to be switched on and off. The CLM2805 is offered in an ultra small package, 5-pin SOT-23 as a fixed, adjustable with ON/OFF Switch. The regulator output voltage may be internally pin-strapped for a 5V, 4.8V, 4.5V, 4V, 3.5V, 3.3V, 3V, 2.5V or programmed from 3V to 24V with an external pair of resistors. For other fix voltages consult the factory.

See TYPICAL APPLICATIONS notes to ensure constant junction temperature, low duty cycle pulse testing used. 2. All limits are at 125oC or over the full operating temperature junction range of -40 oC to +125oC. 3. The maximum power dissipation is a function of maximum junction temperature, total thermal resistance and ambient temperature. 4. Human body model, 100F discharged through 1.5K.
