MIC5246
General Description
The MIC5246 is an efficient, precise CMOS voltage regulator
optimized for low-noise applications. The MIC5246 offers
better than 1% initial accuracy, extremely-low-dropout volt-
age (typically 150mV at 150mA) and constant ground current
(typically 85
μ
A)over load . The MIC5246 features an error
flag that indicates an output fault condition such as overcurrent,
thermal shutdown and dropout. The MIC5246 provides a very
low noise output, ideal for RF applications where quiet
voltage sources are required.
Designed specifically for hand-held and battery-powered
devices, the MIC5246 provides a TTL-logic-compatible en-
able pin. When disabled, power consumption drops nearly to
zero.
The MIC5246 also works with low-ESR ceramic capacitors,
reducing the amount of board space necessary for power
applications, critical in hand-held wireless devices.
Key features include current limit, thermal shutdown, a push-
pull output for faster transient response, and an active clamp
to speed up device turnoff. Available in the IttyBitty SOT-23-5
package, the MIC5246 also offers a range of fixed output
voltages.
