STC2G15 BCMOS VOLTAGE REGULATOR DESIGNED FOR USE WITH VERY LOW ESR AND TANTALUM OUTPUT CAPACITOR ■ ■ ■ ■ ■ ■ ■ ■ INPUT VOLTAGE FROM 2.7V TO 5.02V STABLE WITH LOW ESR CERAMIC AND TANTALUM CAPACITORS VERY LOW QUIESCENT CURRENT (30µA TYP. AT NO LOAD; 2µA IN OFF MODE) GUARANTEED OUTPUT CURRENT UP TO 15mA OUTPUT VOLTAGE: 1.5V LOGIC-CONTROLLED ELECTRONIC SHUTDOWN INTERNAL CURRENT LIMIT JUNCTION TEMPERATURE RANGE: -40°C TO 95°C DESCRIPTION The STC2G15 provides up to 15mA, from 2.5V to 6V input voltage. The low quiescent current makes it suitable for low power applications and in battery powered systems. TSOT23-5L Shutdown Logic Control function is available, this means that when the device is used as local regulator, it is possible to put a part of the board in standby, decreasing the total power consumption. The STC2G15 is designed to work with low ESR ceramic and tantalum capacitors. Typical applications are in mobile phone, blue-tooth module and similar battery powered wireless systems.

Note 2: Time for the output Voltage to fall from 85% to 50 of nominal value. Note 3: Regulator must be able to sustain Regulated Output Voltage without load. Note 4: Parameters are uncritical as long as the output voltage stays within limits. Note 5: A sudden voltage rise/drop of 500mV mustn't bring the output Voltage out of limits. Note 6: Ceramic Capacitors can be used if connected between CMP pin and GNG, instead of VOUT pin and GND. Note 8: Maximum and minimum values are guaranteed in full temperature range. Note 9: Line transient is tested when the input voltage changes from 2.7 to 3.2V in 10µs in full load range. Note 10: Line transient is tested when the input voltage changes from 3.2 to 2.7V in 10µs in full load range. Note 11: Load transient is tested when the load changes from 0.1 to 15mA in 10µs in all the input range Note 13: Response time is defined as the time form the load line step until the output reaches a value within specification (1.41V, 1.59V). Note 14: The maximum power dissipation for the operation depends on the ambient temperature. For TJ =95°C, TA=85°C and RTJA=220°C/W the maximum power can be 0.045W. The maximum power dissipation for operation can be increased by 4.5mW each degree below TA=85°C, and it must be derated by 4.5mW for each degree above 85°C 3/8 STC2G15 TYPICAL PERFORMANCE CHARACTERISTICS (unless otherwise specified CIN = C COMP = SMD X5R COUT = Tant., Tj = 25°C) Figure 1 : Output Voltage vs Temperature Figure 4 : Output Voltage vs Temperature Figure 2 : Output Voltage vs Temperature Figure 5 : Line Regulation vs Temperature Figure 3 : Output Voltage vs Temperature Figure 6 : Load Regulation vs Temperature 4/8 STC2G15 Figure 7 : Inhibit Threshold Voltage vs Temperature Figure 10 : Supply Voltage Rejection vs Output Current Figure 8 : Quiescent Current vs Temperature Figure 11 : Dynamic Precharge Mode VI=5V, I O=0.1 to 15mA, CI = 1µFSMD X7R, CO=2.2µF(tant) Figure 9 : Supply Voltage Rejection vs Temperature Figure 12 : Dynamic Precharge Mode VI=2.7 to 3.7V, I O=15mA, CI = 1µFSMD X7R, CO=2.2µF(tant), t=1ms 5/8 STC2G15 Figure 13 : Dynamic Precharge Mode Figure 15 : Dynamic Precharge Mode VINH=0 to 2V, No load, C I = 1µFSMD X7R, CO=2.2µF(tant) VINH=0 to 2V, I O=15mA, CI = 1µFSMD X7R, CO=1µF(tant) Figure 14 : Dynamic Precharge Mode VINH=0 to 2V, I O=15mA, CI = 1µFSMD X7R, CO=2.2µF(tant) 6/8 STC2G15 TSOT23-5L MECHANICAL DATA mm. mils DIM.
