MIC5238
Ultra-Low Quiescent Current, 150mA µCap LDO Regulator
General Description
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-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.
Features
• Ultra-low input voltage range: 1.5V to 6V
• Ultra-low output voltage: 1.1V 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
Applications
• PDAs and pocket PCs
• Cellular phones
• Battery powered systems
• Low power microprocessor power supplies
