General Description
The MIC5259 is an efficient CMOS voltage regulator optimized
for low-noise applications. It offers 1.5% initial accuracy, low
dropout voltage (300mV at 300mA) and low ground current
(typically 105μA at light load). The MIC5259 provides a very-
low-noise output, ideal for RF applications where a clean
voltage source is required. The MIC5259 has a high PSRR
even at low supply voltages, critical for battery operated
electronics. A noise bypass pin is also available for further
reduction of output noise.
Designed specifically for handheld and battery-powered
devices, the MIC5259 provides a TTL-logic-compatible
enable pin. When disabled, power consumption drops to
nearly zero.
The MIC5259 also works with low-ESR ceramic capacitors,
reducing the amount of board space necessary for power
applications; critical issue in handheld wireless devices.
Key features include current limit, thermal shutdown, faster
transient response, and an active clamp to speed up device
turn-off. The MIC5259 is available in the 6-pin 2mm

2mm
MLF package and the ThinSOT-23-5 package in a wide
range of output voltages.
