LR6232B33M

LESHAN RADIO COMPANY, LTD. Ultra Low Current Consumption 300mA CMOS Voltage Regulator LR6232 Series „ INTRODUCTION The /56232 series are a group of positive voltage regulators manufactured by CMOS technologies with ultra low power consumption and low dropout voltage, which provide large output currents even when the difference of the input-output voltage is small. The /56232 series can deliver 300mA output current and allow an input voltage as high as 8V. The series are very suitable for the battery-powered equipments, such as RF applications and other systems requiring a quiet voltage source. „ FEATURES z z z z Low Quiescent Current: 0.8ȝA Operating Voltage Range: 1.8V̚8V Output Current: 300mA Low Dropout Voltage˖ 110mV@100mA(VOUT=3.3V) Output Voltage: 1.2~ 5.0V High Accuracy: ±2ˁ/±1ˁ˄Typ.˅ High Power Supply Rejection Ratio: 50dB@1kHz Low Output Noise: 27xVOUT ȝVRMS (10Hz~100kHz) Excellent Line and Load Transient Response Built-in Current Limiter, Short-Circuit Protection z z z z z z „ APPLICATIONS z Portable consumer equipments z Wireless Communication Equipments z Radio control systems z Portable Audio Video Equipments z Laptop, Palmtops and PDAs z Ultra Low Power Microcontroller „ BLOCK DIAGRAM „ ORDER INFORMATION /56232ķĸĹĺĻ DESIGNATOR ķ ĸĹ ĺ Ļ Ver0.3 SYMBOL A DESCRIPTION Standard B High Active, pull-down resistor built in, with COUT discharge resistor Integer F M/ MC/ MY M P/PT/PL 1 Output Voltage e.g.1.8V=ĸ:1, Ĺ:8 Package:DFN1X1-4 Package:SOT-23-3 Package:SOT-23-5 Package:SOT-89-3 2% Accuracy 1% Accuracy 1/9 LESHAN RADIO COMPANY, LTD. „ PIN CONFIGURATION SOT-23-3 SOT-23-5 DFN1X1-4 PIN NUMBER SOT-23-3 SOT-89-3 SOT-89-3 PIN NAME FUNCTION M MC MY P PT PL 1 3 3 1 2 2 VSS Ground 2 2 1 3 1 3 VOUT Output 3 1 2 2 3 1 VIN Power input SOT-23-5 PIN NUMBER SYMBOL FUNCTION 1 VIN Power Input Pin 2 VSS Ground 3 CE Chip Enable Pin 4 NC No Connection 5 VOUT Output Pin DFN1X1-4 PIN NUMBER SYMBOL FUNCTION 1 VOUT 2 VSS 3 CE 4 VIN Output Pin Ground Chip Enable Pin Power Input Pin F „ ABSOLUTE MAXIMUM RATINGS(1) (Unless otherwise specified, TA=25°C) PARAMETER SYMBOL RATINGS UNITS Input Voltage(2) VIN -0.3~9 V Output Voltage VOUT -0.3~VIN+0.3 V Output Current IOUT 600 mA 0.4 W 0.4 W 0.6 W 0.6 W Tj -40~125 °C Tstg -40~125 °C Tsolder 260 °C (2) SOT-23 Power Dissipation DFN1X1-4 SOT-89 PD TO-92 Operating Junction Temperature Range Storage Temperature Lead Temperature(Soldering, 10 sec) 2/9 LESHAN RADIO COMPANY, LTD.
