DS21662C-page 3 TC2014/2015/2185 Power Supply Rejection Ratio PSRR — 55 — dB F ≤ 1 kHz, Cbypass=0.01 µF Output Short Circuit Current IOUTSC — 160 300 mA VOUT = 0V Thermal Regulation ∆VOUT/∆PD —0.04 — V/W Note 6, Note 7 Output Noise eN — 200 — nV/ √Hz IL = IOUTMAX, F = 10 kHz 470 pF from Bypass to GND Response Time, (Note 8) (from Shutdown Mode) TR —60 — µsec VIN = 4V, IL = 30 mA, CIN = 1 µF, COUT = 10 µF SHDN Input SHDN Input High Threshold VIH 60 —— %VIN VIN = 2.5V to 6.0V SHDN Input Low Threshold VIL —— 15 %VIN VIN = 2.5V to 6.0V ELECTRICAL CHARACTERISTICS (CONTINUED) Electrical Specifications: Unless otherwise specified, VIN = VR + 1V, IL = 100 µA, COUT = 3.3 µF, SHDN > VIH, TA = +25°C. BOLDFACE type specifications apply for junction temperature of -40°C to +125°C. Parameters Sym Min Typ Max Units Conditions Note 1: The minimum VIN has to meet two conditions: VIN = 2.7V and VIN = VR + VDROPOUT. 2: VR is the regulator output voltage setting. For example: VR = 1.8V, 2.7V, 2.8V, 2.85V, 3.0V, 3.3V. 3: 4: Regulation is measured at a constant junction temperature using low duty cycle pulse testing. Load regulation is tested over a load range from 1.0 mA to the maximum specified output current. Changes in output voltage due to heating effects are covered by the thermal regulation specification. 5: Dropout voltage is defined as the input-to-output differential at which the output voltage drops 2% below its nominal value at a V differential. 6: Thermal Regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied, excluding load or line regulation effects. Specifications are for a current pulse equal to IMAX at VIN = 6V for T = 10 msec. 7: The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction tem- perature and the thermal resistance from junction-to-air (i.e. TA, TJ, θJA). 8: Time required for VOUT to reach 95% of VR (output voltage setting), after VSHDN is switched from 0 to VIN.
