Description

The FAN2500 micropower low-dropout voltage regulator

utilizes CMOS technology to offer a new level of cost-

effective performance in mobile handsets, laptop and

notebook portable computers, and other portable

devices. Features include extremely low power consump-

tion, low shutdown current, low dropout voltage, excep-

tional loop stability able to accommodate a wide variety of

external capacitors, and a compact SOT23-5 surface-

mount package. The FAN2500 offers significant improve-

ments over older BiCMOS designs and is pin-compatible

with many popular devices. The output is thermally pro-

tected against overload.

FAN2500: pin 4 – ADJ, allows the user to adjust the

output voltage over a wide range using an external volt-

age divider.

FAN2500-XX: pin 4 – BYP, to which a bypass capacitor

may be connected for optimal noise performance. Output

voltage is fixed, indicated by the suffix XX.

The standard fixed output voltages available are 2.5 V,

3.0 V, and 3.3 V.

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Parameter Min. Max.

Designed utilizing CMOS process technology, the FAN2500 is carefully optimized for use in compact battery-powered devices. The FAN2500 offers a unique combination of low power consumption, extremely low dropout voltages, high tolerance for a variety of output capacitors, and the ability to disable the output to less than 1 μA under user control.
PAGE 10
FAN2500 can supply high peak output currents of up to 1 A for brief periods. However, this output load causes the device temperature to exceed maximum ratings due to power dissipation. During output overload conditions, when the die temperature exceeds the shutdown limit temperature of 150°C, onboard thermal protection disables the output until the temperature drops below this limit, at which point the output is re-enabled.
