PARAMETER TEST CONDITIONS MIN TYP MAX UNIT 4. Input Voltage (VIN pin) Fixed 5-V output, IOUT = 1 mA 5.3 40 4.1 VIN Input voltage V Fixed 3.3-V output, IOUT = 1 mA 3.6 40 4.2 IQUIESCENT Quiescent current VIN = 8.2 V to 18 V, IOUT = 0.01 mA to 0.75 mA 25 40 µA Undervoltage lockout 4.3 VIN-UVLO Ramp VIN down until output is turned OFF 3.16 V voltage 4.4 VIN(POWERUP) Power-up voltage Ramp VIN up until output is turned ON 3.45 V 5. Regulated Output Voltage (VOUT pin) Fixed VOUT value (3.3 V or 5 V as applicable), 5.1 VOUT Regulated output voltage IOUT = 10 mA, 10 mA to 300 mA, –2% 2% VIN = VOUT + 1 V to 16 V VIN = 6 V to 28 V, IOUT = 10 mA, VOUT = 5 V 15 mV 5.2 ∆VLINE-REG Line regulation VIN = 6 V to 28 V, IOUT = 10 mA, VOUT = 3.3 V 20 mV IOUT = 10 mA to 300 mA, VIN= 14 V, VOUT = 5 V 25 mV 5.3 ∆VLOAD-REG Load regulation IOUT = 10 mA to 300 mA,VIN = 14 V, VOUT = 3.3 V 35 mV IOUT = 250 mA 500 mV Dropout voltage 5.4 VDROPOUT (1) (VIN – VOUT) IOUT = 150 mA 300 mV 5.5 RSW (2) Switch resistance VIN to VOUT resistance 2 Ω 5.6 IOUT Output current VOUT in regulation 0 300 mA 5.7 ICL Output current limit VOUT = 0 V (VOUT pin is shorted to ground) 350 1000 mA VIN-RIPPLE = 0.5 Vpp, IOUT = 300 mA, frequency = 100 Hz, VOUT = 5 V, and 60 VOUT = 3.3 V Power-supply ripple 5.8 PSRR(2) dB rejection VIN-RIPPLE = 0.5 Vpp, IOUT = 300 mA, frequency = 150 kHz, VOUT = 5 V, and 30 VOUT = 3.3 V 6. Operating Temperature Range Operating junction 6.1 TJ -40 150 ºC temperature Thermal shutdown trip 6.2 TSHUTDOWN 165 ºC point Thermal shutdown 6.3 THYST 10 ºC hysteresis (1) This test is done with VOUT in regulation and VIN – VOUT parameter is measured when VOUT (3.3 V or 5 V) drops by 100 mV at specified loads.
