GM6353 450mA ULTRA LOW DROPOUT POSITIVE VOLTAGE REGULATOR Description Features GM6353 series is a group of positive voltage output, three-pin regulators, that provide a high current even when the input/output voltage differential is small. Low power consumption and high accuracy is achieved through CMOS and programmable fuse technologies, with the output voltage range from 1.5V to 6.0V GM6353 consists of a high precision voltage reference, an error correction circuit, and a current limited output driver. Transient response to load variations has been improved in comparison to the existing series. The GM6353 incorporates both over temperature and over current protection. Maximum output current up 450mA Output voltage from 1.5V to 6.0V in 0.1V increments Output voltage accuracy : ±2% CMOS low power consumption, typically 15µA Input stability: typically 0.2%/V Ultra low dropout voltage, 0.1V @ IOUT = 100mA Application Palmtops Battery Powered Equipment Portable Cameras Reference Voltage Sources Video Recorders Typical Application Circuits GM6350-x.x VOUT VIN CIN 1µF (Tantalum) RL VSS COUT 1µF (Tantalum) GM6353V2.00 VIN www.gammamicro.com.tw 1 GM6353 450mA ULTRA LOW DROPOUT POSITIVE VOLTAGE REGULATOR Marking Information and Pin Configurations (Top View) SOT223 GM6353G VVAYWW 1 GND 2 VOUT GM6350V2.00 G: Green Product VV: Voltage suffix (18 = 1.8V, 50 = 5.0V…) A: Assembly / Test Site Code Y: Year WW: Week 2 3 VIN GM6353 450mA ULTRA LOW DROPOUT POSITIVE VOLTAGE REGULATOR Ordering Number Output Voltage Package Shipping GM6353-1.5ST3RG 1.5V SOT-223 2,500 Units/Tape and Reel GM6353-1.8ST3RG 1.8V SOT-223 2,500 Units/Tape and Reel GM6353-2.5ST3RG 2.5V SOT-223 2,500 Units/Tape and Reel GM6353-3.3ST3RG 3.3V SOT-223 3,000 Units/Tape and Reel GM6353-5.0ST3RG 5.0V SOT-223 3,000 Units/Tape and Reel GM6353V2.00 Ordering Information 3 GM6353 450mA ULTRA LOW DROPOUT POSITIVE VOLTAGE REGULATOR Absolute Maximum Ratings PARAMETER SYMBOL RATINGS UNITS Input Voltage VIN 6.5 V Output Current IOUT 450 mA Output Voltage VOUT VSS – 0.3 to VIN +0.3 V SOT-223 θJA 15 °C/W Maximum Operating Junction Temperature TJ 150 °C Operating Ambient Temperature TA - 40 to 125 °C Storage Temperature Tstg - 65 to 150 °C + 260 °C Thermal Resistance, Junction to Case Lead Temperature (Soldering, 10 sec) Block Diagram VIN VOUT Current Limit Voltage Reference GM6350V2.00 VSS 4 GM6353 450mA ULTRA LOW DROPOUT POSITIVE VOLTAGE REGULATOR Electrical Characteristics (TA = 25°C, VIN = VOUT + 0.5V unless otherwise noted) Parameter Symbol Output Voltage Accuracy Load Regulation +1.4 IOUT = 0.1mA to 300mA -3.0 +2.0 ∆VOL VIN = 6V, 0.1mA < IOUT < 300mA COUT = 1µF, Fig. 2 VIN = 5V, VOUT > 0.96 X VRATING ICL Ground Pin Current IGND Unit 300 0.1 0.3 %/V 0.005 0.04 %/mA 500 mA 400 VOUT > 2.5V 2.0V <VOUT < 2.5V Max -1.4 IOUT = 1mA, VOUT + 0.1V < VIN < 6.5V Fig. 1 Output Current Limit Typ IOUT = 1mA ∆VOI Maximum Output Current Dropout Voltage Min % VOUT Line Regulation Condition ∆V VOUT < 2.0V mA Fig. 3 15 30 µA IOUT = 100mA 100 180 IOUT = 300mA 300 550 IOUT = 100mA 150 300 IOUT = 300mA 450 800 IOUT = 100mA 200 400 IOUT = 300mA 600 1100 mV Power Supply Rejection PSRR 10kHz Ration Note: Load Regulation is measured using pulse techniques with duty cycle < 5% 60 dB 6.5V VOUT + 0.1V VIN GM6353-x.x VOUT 6V VIN GM6353-x.x VOUT 300mA 1mA Figure 1.
