Description

General part information

MIC5238 Series

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.

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-mode current 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.
