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
with low-cost, small-capacitance ceramic capacitors.
The devices are available as the standard products listed in Table 1 .

?? Guaranteed 150mA / 300mA Output
?? 1.25V Internal Reference
?? Extremely-Low Quiescent Current: 40μA
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.
?? Excellent Load/Line Transient
?? Overcurrent and Thermal Protection
?? TSOT23 5-pin Package
3 Applications
The devices are ideal for mobile phones, wireless phones, PDAs,
handheld computers, mobile phone base stations, Bluetooth portable
radios and accessories, wireless LANs, digital cameras, personal
audio devices, and any other portable, battery-powered application.
