TLV70228DBVR Datasheet PDF - TI

●DESCRIPTION

●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 μF(1)

●• Thermal Shutdown and Overcurrent Protection

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

●(1) See the Input and Output Capacitor Requirements in the Application Information section.
