GM6251 ULTRA - LOW DROPOUT POSITIVE VOLTAGE REGULATOR Power Management Description The GM6251's combine high accuracy with very low power consumption, providing high output current even when the application requires extremely low input-output voltage differential. The GM6251's include a precision voltage reference, an error correction circuit, over-temperature protection, and a current limited output driver. Fast transient response to load variations provides excellent stability under dynamic load conditions. The GM6251's come in SOT-25 (150mW), SOT-89 (500mW) and TO-92 packages. Features Maximum output current 250mA (within maximum power dissipation) Output voltage: from 1.8 V to 6.0V in 0.1V increments Output voltage ±2% CMOS low power consumption, typically 1.0µA at VOUT = 5.0V Input stability typically 0.2%/ V Ultra-low dropout voltage 0.38V @ IOUT = 200mA at VOUT = 5.0V Small input/ output differential: 0.4V at 160mA (VOUT = 3.3V) SOT-25 (150mW), SOT-89 (500mW) and TO-92 packages Application Palmtops Portable Cameras Video Recorders Battery Powered Equipment Reference Voltage Sources VIN VIN GM6251 VOUT VSS CL 1µF (Tantalum) 1µF (Tantalum) www.gammamicro.com PRELIMINARY GM6251 1 +C + IN RL Revision 1, Jun. 2004 TYPICAL APPLICATION CIRCUITS GM6251 MARKING INFORMATION & PIN CONFIGURATIONS(TOP VIEW) SOT-25(SOT-23-5) TO-92 SOT-89 VOUT 5 NC 4 6251 VV AYWW 1.

Please use this IC within the stipulated absolute maximum ratings as the IC is liable to malfunction outside of such parameters. 2. There is a possibility theat oscillation may occur as a result of the impedance present between the power supply and the IC's input. Where impedance is 10W or more, please use a capacitor (CIN) of at least 1µF. With a large output current, operations can be stabilised by increasing capacitor size (CIN). If CIN is small and capacitor size (CL) is increased, there is a possibility of oscillation due to input impedance. In such cases, operations can be stabilised by either increasing the size of CIN of decreasing the size of CL. 3. Please ensure that output current (IOUT) is less than Pd ÷ (VIN - VOUT) and does not exceed the stipulated continuous total power dissipation value (Pd) for the package.
