Low-Noise, High PSRR,
Low-Dropout, 120mA Linear Regulator
General Description
The MAX8940 low-noise, low-dropout (LDO) linear reg-
ulator is designed to deliver up to 120mA continuous
output current. This regulator achieves a low 120mV
dropout for 120mA load current. The MAX8940 uses an
advanced architecture to achieve low output voltage
Features
? Space-Saving SC70
? 25 μ V RMS Output Noise at 100Hz to 100kHz
Bandwidth
? 65dB PSRR at 10kHz
noise of 25μV RMS and PSRR of 45dB at 100kHz.
?
120mV Dropout at 120mA Load
The MAX8940 is preset to either 2.8V or 3.0V. Designed
with a p-channel MOSFET series pass transistor, the
MAX8940 maintain very low ground current (40μA).
The regulator is designed and optimized to work with low-
value, low-cost ceramic capacitors. The MAX8940
requires only 1μF (typ) of output capacitance for stability
with any load. When disabled, current consumption drops
to below 1μA.
Package is a 5-pin SC70.
Applications
Cellular and Cordless Phones
PDA and Palmtop Computers
Base Stations
Bluetooth Portable Radios and Accessories
Wireless LANs
Digital Cameras
Personal Stereos
Portable and Battery-Powered Equipment
? Stable with 1 μ F Ceramic Capacitor for Any Load
? Guaranteed 120mA Output
? Output Voltages: 2.8V or 3V
? Low 40 μ A Ground Current
? Excellent Load/Line Transient
? Overcurrent and Thermal Protection
