TLV70245DBVR
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
