MIC5259
300mA High PSRR, Low Noise μCap CMOS LDO
General Description
Features
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 speci ? cally 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

Input voltage range: 2.7V to 6.0V
PSRR = 70dB @ 1kHz
Low output noise: 30μV(rms)
Stability with ceramic output capacitors
Low-dropout: 300mV @ 300mA
High-output accuracy:
– 1.5% initial accuracy
– 3.0% over temperature
Low quiescent current: 105μA
Tight load and line regulation
TTL-Logic-controlled enable input
“Zero” off-mode current
capacitors, reducing the amount of board space necessary
for power applications; critical issue in handheld wireless
devices.
? Thermal shutdown and current limit protection
Applications
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 5-pin Thin SOT-23
package in a wide range of output voltages.
