MIC5238

Ultra-Low Quiescent Current, 150mA

µCap LDO Regulator

General Description

Features

The MIC5238 is an ultra-low voltage output, 150mA LDO

regulator. Designed to operate in a single supply or dual

supply mode, the MIC5238 consumes only 23µA of bias

current, improving efficiency. When operating in the dual

supply mode, the efficiency greatly improves as the higher

voltage supply is only required to supply the 23µA bias

current while the output and base drive comes off of the

much lower input supply voltage.

• Ultra-low input voltage range:1.5V to 6V

• Ultra-low output voltage:1.0V minimum output voltage

• Low dropout voltage: 310mV at 150mA

• High output accuracy: ±2.0% over temperature

• µCap: stable with ceramic or tantalum capacitors

• Excellent line and load regulation specifications

• Zero shutdown current

• Reverse leakage protection

• Thermal shutdown and current limit protection

• IttyBitty^®SOT-23-5 package

As a µCap regulator, the MIC5238 operates with a 2.2µF

ceramic capacitor on the output, offering a smaller overall

solution. It also incorporates a logic-level enable pin that

allows the MIC5238 to be put into a zero off-current mode

when disabled.

The MIC5238 is fully protected with current limit and

thermal shutdown. It is offered in the IttyBitty^®SOT-23-5

package with an operating junction temperature range of

–40°C to +125°C.

Applications

• PDAs and pocket PCs

• Cellular phones

• Battery powered systems

• Low power microprocessor power supplies
