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

surface-mount package. In addition, the FAN2518/19 family

offer the fast power-cycle time required in CDMA handset

applications. These products offer signiﬁcant improvements

over older BiCMOS designs and are pin-compatible with

many popular devices. The output is thermally protected

Features

• Ultra Low Power Consumption

• Enable optimized for CDMA time phases

• 50 mV dropout voltage at 50 mA

• 25 µA ground current at 50 mA

• Enable/Shutdown Control

against overload.

• SOT23-5 package

• Thermal limiting

• 300 mA peak current

The FAN2518 and FAN2519 devices are distinguished by

the assignment of pin 4:

FAN2518: 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

FAN2518-XX: pin 4 – BYP, to which a bypass capacitor

• Laptop, notebook and palmtop computers

may be connected for optimal noise performance. Output

voltage is ﬁxed, indicated by the sufﬁx XX.

Description

The FAN2518/19 family of micropower low-dropout voltage

regulators utilize CMOS technology to offer a new level of

cost-effective performance in GSM, TDMA, and CDMA

FAN2519-XX: pin 4 – ERR, a ﬂag which indicates that the

output voltage has dropped below the speciﬁed minimum

due to a fault condition.

cellular handsets, Laptop and Notebook portable computers,

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

and other portable devices. Features include extremely low

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