MIC5254
Dual 150mA
μ
Cap LDO with Error Flag Outputs
General Description
The MIC5254 is an efficient, precise, dual CMOS voltage
regulator. It offers better than 1% initial accuracy, extremely
low dropout voltage (typically 135mV at 150mA) and low
ground current (typically 90
μ
A) over load. The MIC5254
features two independent LDOs with error flags that indicate
an output fault condition such as overcurrent, thermal shut-
down and dropout.
Designed specifically for handheld and battery-powered de-
vices, the MIC5254 provides a TTL-logic-compatible enable
pin. When disabled, power consumption drops nearly to zero.
The MIC5254 also works with low-ESR ceramic capacitors,
reducing the amount of board space necessary for power
applications, critical in handheld wireless devices.
Key features include current limit, thermal shutdown, faster
transient response, and an active clamp to speed up device
turnoff. The MIC5254 is available in the MSOP-10 package
and is rated over a –40
°
C to +125
°
C junction temperature
range.
