4 / 11 page  YB1231 HV600mA, Low-Noise LDO Regulator YB1231 Rev.1.6 www.yobon.com.tw 4 Electrical Characteristics Table 2 VIN = ( VOUT + 1V ), CIN = COUT = 2.2μF, VEN = VIN, TA=25°C, unless otherwise noted. Description Symbol Test Conditions MIN TYP MAX Units Input Voltage Range VIN 2.0 5.5 V Output Voltage VOUT Predefined 3.2 4.5 V Output Voltage Accuracy ΔVOUT IOUT = 10mA -2.0 +2.0 % Output Current Limit ISC Short-Circuit Output 420 mA VOUT = 4.5V, IOUT = 600mA 440 VOUT = 4.0V, IOUT = 600mA 470 VOUT = 3.6V, IOUT = 600mA 500 VOUT = 3.3V, IOUT = 600mA 530 Dropout Voltage (Note 1) VDROP VOUT = 3.2V, IOUT = 600mA 550 mV Ground Current IG Iground = IIN - IOUT 100 160 μA Line Regulation ΔVLINE VIN=(VOUT+1V) to 5.5V, IOUT=10mA 0.4 %/V Load Regulation ΔVLOAD IOUT = 1mA to 600mA 1.7 % Shutdown Supply Current ISD EN = 0V 1 μA f = 100Hz, IOUT = 10mA 51 f = 1KHz, IOUT = 10mA 51 Ripple Rejection (PSRR) PSRR f = 10KHz, IOUT = 10mA 45 dB Shutdown Exit Delay (Note 2) VOUT = 3.3V, Rload = 11 ohm 36 100 μs EN Logic Low Level VIL VIN = 2.0V to 5.5V 0.4 V EN Logic High Level VIH VIN = 2.0V to 5.5V 1.5 VIN V EN Input Bias Current IBEN VIN = EN = VOUT +1V 0.01 μA Thermal Shutdown TSD Shutdown Temperature 160 °C Thermal Hysteresis THYS VOUT = 3.3V, IOUT = 100mA 20 °C Note : 1. The drop out voltage varies depending on output voltage selection. Dropout is defined as VIN – VOUT when VOUT is 100mV below nominal VOUT where VIN = VOUT + 1V for nominal VOUT. 2. Time needed for VOUT to reach 90% of final value. |
