4 / 12 page  YB1210R 300mA, Ultra-Low-Noise, High PSRR LDO Regulator YB1210R Rev.1.6 www.yobon.com.tw 4 Electrical Characteristics Table 2 VIN = ( VOUT + 1V ), CIN = COUT = 1.0μF, 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 1.2 3.6 V IOUT = 10mA, VOUT ≧ 1.3V -2.0 +2.0 Output Voltage Accuracy Δ VOUT IOUT = 10mA, VOUT = 1.2V 0 +4.0 % Output Current Limit ISC Short-Circuit Output 200 mA VOUT = 3.6V, IOUT = 300mA 300 VOUT = 3.0V, IOUT = 300mA 350 VOUT = 2.5V, IOUT = 300mA 450 VOUT = 1.5V, IOUT = 300mA 700 Dropout Voltage (Note 1) VDROP VOUT = 1.2V, IOUT = 300mA 870 mV Ground Current IG Iground = IIN - IOUT 60 μA Line Regulation Δ VLINE VIN=(VOUT+ 1V) to 5.5V, IOUT=10mA 0.3 0.4 %/V Load Regulation Δ VLOAD IOUT = 1mA to 300mA 1.0 1.5 % Shutdown Supply Current ISD EN = 0V 1 μA f = 1KHz, IOUT = 1mA 50 f = 10KHz, IOUT = 1mA 60 Ripple Rejection (PSRR) PSRR f = 100KHz, IOUT = 1mA 40 dB Rload = 100 ohm, Cbypass = 0nF 20 50 μs Start Up Delay (Note 2) Rload = 100 ohm, Cbypass = 33nF 2 3.5 ms Rload = 10K ohm, VOUT = 1.5V 1 Shutdown Delay (Note 3) Rload = 10K ohm, VOUT = 1.2V 1 ms 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 1.2 VIN V EN Input Bias Current IBEN VIN = EN = VOUT +1V 0.01 μA Thermal Shutdown TSD Shutdown Temperature 160 °C Thermal Hysteresis THYS 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. 3. Time needed for VOUT to discharge below 0.5V. |
