LD39020: miniaturized low Iq, high performance LDO

The LD39020 is a miniaturized low-consumption LDO able to provide up to 200 mA current from an input voltage ranging from 1.5 to 5.5 V.
Housed in the new tiny DFN4 package  with a footprint of only 1x1mm2, LD39020 features an initial accuracy up to 0.5%, a very high power supply rejection of 80dB at 1kHz and a low quiescent current of 20 µA .
LD39020 is the ideal power supply linear regulators for the space-constrained hand-held applications, such as the last generation smartphones, tablets and portable entertainment devices.
It is available in many different options covering a range of output voltages from 0.8 V to 5 V in 50 mV steps. 

Ultra-tiny low-dropout regulator in breakthrough bumpless chip-scale package

The LDBL20 is a powerful 200 mA LDO in a tiny 0.47 x 0.47 mm innovative ST STAMP™ chip-scale package. The input voltage can range from 1.5 to 5.5 V, with 200 mV typical dropout. Rejection (PSRR) of 80 dB at 100 Hz and 50 dB at 100 kHz simplifies filtering over a wide frequency range to provide a stable rail for low-power circuitry in battery-operated applications. Quiescent current of 20 µA no-load, 100 µA full-load, and 0.3 µA in standby help maximize efficiency under all operating conditions.
