5 / 21 page LP2966 www.ti.com SNVS028E – APRIL 2000 – REVISED APRIL 2013 ELECTRICAL CHARACTERISTICS (continued) Limits in standard typeface are for Tj = 25°C, and limits in boldface type apply over the full operating junction temperature range. Unless otherwise specified, VIN = VO(NOM) + 1V (1), C OUT = 1µF, IOUT = 1mA, CIN = 1µF, VSD1 = VSD2 = VIN. LP2966IMM(3) Symbol Parameter Conditions Typ(2) Unit Min Max Over Temperature Protection Tsh(t) Shutdown Threshold 165 °C Tsh(h) Thermal Shutdown 25 °C Hysteresis Shutdown Input VSDT Shutdown Threshold(12) Output = Low 0 0.1 V Output = High VIN VIN - 0.1 TdOFF Turn-off Delay(13) IL = 100 mA 20 µsec TdON Turn-on Delay(13) IL = 100 mA 25 µsec ISD SD Input Current VSD = VIN 1 nA VSD = 0 V 1 Error Flag Comparators VT Threshold (output goes See(14) 10 5 16 % high to low) VTH Threshold Hysteresis See(14) 5 2 8 % VERR(Sat) Error Flag Saturation IFsink = 100µA 0.015 0.1 V IEF(leak) Error Flag Pin Leakage 1 nA Current I(EFsink) Error Flag Pin Sink 1 mA Current AC Parameters PSRR Ripple Rejection VIN = VOUT + 1V, f = 120Hz, 60 VOUT = 3.3V dB VIN = VOUT + 0.3V, f = 120Hz, 40 VOUT = 3.3V ρn(1/f) Output Noise Density f =120Hz 1 µV/ √Hz en Output Noise Voltage BW = 10Hz − 100kHz, 150 (rms) COUT = 10µF µV(rms) BW = 300Hz − 300kHz, 100 COUT = 10µF (12) VSDT is the shutdown pin voltage threshold below which the output is disabled. (13) Turn-on delay is the time interval between the low to high transition on the shutdown pin to the output voltage settling to within 5% of the nominal value. Turn-off delay is the time interval between the high to low transition on the shutdown pin to the output voltage dropping below 50% of the nominal value. The external load impedance influences the output voltage decay in shutdown mode. (14) Error Flag threshold and hysteresis are specified as the percentage below the regulated output voltage.
