简  介: www.fairchildsemi.com FAN1950/FAN1951 1.5A Low-Voltage Low-Dropout Regulator Features 1.5A minimum guaranteed output current 500mV maximum dropout at 1.5A Ideal for 2.5V to 1.8V or 1.65V conversion Ideal for 3.0V to 2.5V conversion Current Limiting and Thermal shutdown External Shut-down control (FAN1951 only) Error ag output (FAN1951 only) Fast transient response Low ground current General Description The FAN1950 and FAN1951 are 1.5A low-dropout linear regulators that provide a low voltage, high current output with a minimum of external components. Both of these devices use a PNP output pass element achieving a maximum 500mV dropout at 1.5A load current. In addition these devices offer overcurrent limit and thermal shutdown features to ensure full protection. The FAN1951 offers a logic level enable pin and an error ag output to indicate undervoltage and over-current conditions. 1.8V and 2.5V xed output versions are available. 3.3V, 1.65V and 1.5V options are available upon request. Applications General purpose conversion for low-voltage CPUs, DSP and FPGAs SMPS post regulator Cable/Satellite set-top boxes PCI Graphics adapter cards Typical Application FAN1950-2.5V 3.0V IN OUT GND 2.5V 10F 100K Error Output On/Off FLAG EN GND FAN1951-1.8V 2.5V IN OUT 1.8V 10F REV. 0.1.6 8/30/04 FAN1950/FAN1951 Pin Assignments FAN1950Dx FRONT VIEW FAN1951Dx FRONT VIEW 1 2 3 1 2 3 4 5 GND (TAB) GND (TAB) OUT EN OUT IN IN 3-Lead Plastic TO-252 (DPAK) 5-Lead P……
