REGULATED OUTPUT VOLTAGE (VOUT Pin)
VOUT Regulated output voltage Fixed VOUT value (3.3 V or 5 V as applicable),
IOUT = 10 mA, 10 mA to 300 mA,
VIN = VOUT + 1 V to 16 V		 –2% 2%
∆VLINE-REG Line regulation VIN = 6 V to 28 V, IOUT = 10 mA, VOUT = 5 V 15 mV
VIN = 6 V to 28 V, IOUT = 10 mA, VOUT = 3.3 V 20
∆VLOAD-REG Load regulation IOUT = 10 mA to 300 mA, VIN= 14 V, VOUT = 5 V 25 mV

RSW(3) Switch resistance VIN to VOUT resistance 2 Ω
IOUT Output current VOUT in regulation 0 300 mA
ICL Output current limit VOUT = 0 V (VOUT pin is shorted to ground) 350 1000 mA
PSRR(3) Power-supply ripple rejection VIN-RIPPLE = 0.5 Vpp, IOUT = 300 mA,
frequency = 100 Hz, VOUT = 5 V, VOUT = 3.3 V		 60 dB

TSHUTDOWN Thermal shutdown trip point 165 ºC
THYST Thermal shutdown hysteresis 10 ºC
(1) VIN can go down to 4 V for 130 ms or less and remain functional. If VIN is less than 7 V for longer than 130 ms, then some devices may turn off until the input voltage rises above 7 V.
(2) 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.
(3) Specified by design; not tested.
