AS1361/AS1362
150mA/300mA, Ultra-Low-Noise, High-PSRR
Low Dropout Regulators, with POK
1 General Description

Revision 1.03

Datasheet
The AS1361/AS1362 are ultra-low-noise, low-dropout
linear regulators specifically designed to deliver up to
150/300mA continuous output current, and can achieve
a low 140mV dropout for 300mA load current. The LDOs
are designed and optimized to work with low-cost, small-
capacitance ceramic capacitors.
The devices are available as the standard products
listed in
Table 1
.
Table 1. Standard Products
An integrated P-channel MOSFET pass transistor allows
the devices to maintain extremely low quiescent current
(40μA).
The AS1361/AS1362 uses an advanced architecture to
achieve ultra-low output voltage noise of 9μV
RMS
and a
power-supply rejection-ratio of better than 80dB (up to
10kHz).
An active-Low, open-drain power-ok output indicates if
the output voltage is within regulation.
The AS1361/AS1362 requires only 1μF output capacitor
for stability at any load. When the LDO is disabled, cur-
rent consumption drops below 500nA.
The devices are available in a TSOT23 6-pin package.
