AS1358 / AS1359
150mA/300mA, Ultra-Low-Noise, High-PSRR Low Dropout Regulators

Revision 1.5

Datasheet
1 General Description
The AS1358 / AS1359 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
.
An integrated P-channel MOSFET pass transistor allows the devices
to maintain extremely low quiescent current (40μA).
The AS1358 / AS1359 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).
The AS1358 / AS1359 requires only 1μF output capacitor for stability
at any load. When the LDO is disabled, current consumption drops
below 500nA.
The devices are available in a TSOT23 5-pin package.
