G953 Global Mixed-mode Technology Inc. 1.5A Low Dropout Regulator Features General Description The G953 is a high performance positive voltage regulator designed for use in applications requiring very low dropout voltage at up to 1.5 Amps. G953 features 500mV dropout voltages and very low ground current. Although designed for high current loads, these devices are also useful in lower current, extremely low dropout-critical systems, where their minimal dropout voltage and ground current values are important characteristics. Fixed output voltage Output current up to 1.5A Over current and over temperature protection Low dropout voltage [email protected] Low ground current SOT-223 package Applications Battery powered systems Motherboards Peripheral cards Network cards Set Top Boxes Notebook Computers The G953 provides excellent regulation over variations in line, load and temperature.
