MIC5238
Ultra-Low Quiescent Current, 150mA
μ
Cap 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 23
μ
A 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 23
μ
A bias
current while the output and base drive comes off of the much
lower input supply voltage.
As a
μ
Cap regulator, the MIC5238 operates with a 2.2
μ
F
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.
