TLV70228PDBVT

300毫安，低IQ ，低压降稳压器 300-mA, Low-IQ, Low-Dropout Regulator

DESCRIPON

The TLV702xx series of low-dropout LDO linear regulators are low quiescent current devices with

excellent line and load transient performance. These LDOs are designed for power-sensitive applications. A precision bandgap and error amplifier provides overall 2% accuracy. Low output noise, very high power-supply rejection ratio PSRR, and low-dropout voltage make this series of devices ideal for a wide selection of battery-operated handheld equipment. All device versions have thermal shutdown and current limit for safety.

FEATURES

• Very Low Dropout:

– 37 mV at IOUT = 50 mA, VOUT = 2.8 V

– 75 mV at IOUT = 100 mA, VOUT = 2.8 V

– 220mV at IOUT = 300 mA, VOUT = 2.8 V

• 2% Accuracy

• Low IQ : 35 μA

• Fixed-Output Voltage Combinations Possible from 1.2 V to 4.8 V

• High PSRR: 68 dB at 1 kHz

• Stable with Effective Capacitance of 0.1 μF1

• Thermal Shutdown and Overcurrent Protection

• Packages: SOT23-5 and 1,5mm × 1,5mm SON-6
