5 0 m A CMOS LDO Re g u la t o rs

wide variety of external capacitors, and the compact SOT23-5

surface-mount package. The FAN2508/09 family of products

offer signiﬁcant improvements over older BiCMOS designs

and are pin-compatible with many popular devices. The

output is thermally protected against overload.

Features

• Ultra Low Power Consumption

• 50 mV dropout voltage at 50 mA

• 25 µA ground current at 50 mA

• Enable/Shutdown Control

• SOT23-5 package

The FAN2508 and FAN2509 devices are distinguished by

the assignment of pin 4:

• Thermal limiting

• 300 mA peak current

FAN2508: pin 4 – ADJ, allowing the user to adjust the

output voltage over a wide range using an external voltage

divider.

Applications

• Cellular Phones and accessories

• PDAs

• Portable cameras and video recorders

• Laptop, notebook and palmtop computers

FAN2508-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.

Description

FAN2509-XX: pin 4 – ERR, a ﬂag which indicates that the

output voltage has dropped below the speciﬁed minimum

due to a fault condition.

The FAN2508/09 family of micropower low-dropout voltage

regulators utilize CMOS technology to offer a new level of

cost-effective performance in GSM and TDMA cellular

handsets, Laptop and Notebook portable computers, and

other portable devices. Features include extremely low

power consumption and low shutdown current, low dropout

voltage, exceptional loop stability able to accommodate a

The standard ﬁxed output voltages available are 2.5V, 2.6V,

2.7V, 2.8V, 2.85V, 3.0V, and 3.3V. Custom output voltage are

also available: please contact your local Fairchild Sales
