LT3150

Fast Transient Response,

Low Input Voltage, Very Low Dropout

Linear Regulator Controller

FEATURES

DESCRIPTIO

TheLT^®3150drivesalowcostexternalN-channelMOSFET

as a source follower to produce a fast transient response,

very low dropout voltage linear regulator. Selection of the

N-channelMOSFETR_DS(ON)allowsdropoutvoltagesbelow

300mV for low V_INto low V_OUTapplications.

■

Fast Transient Response Optimized with

Ceramic Output Capacitors

■

FET R_DS(ON)Defines Dropout Voltage

■

±1% Reference Tolerance Over Temperature

Multifunction LDO Shutdown Pin with Latchoff

Fixed Frequency 1.4MHz Boost Converter Generates

MOSFET Gate Drive

■

The LT3150 includes a fixed frequency boost regulator

that generates gate drive for the N-channel MOSFET. The

internally compensated current mode PWM architecture

combined with the 1.4MHz switching frequency permits

the use of tiny, low cost capacitors and inductors.

■

Internally Compensated Boost Converter Uses Tiny

Capacitors and Inductor

Independent Boost Converter Shutdown Control

Permits LDO Output Voltage Supply Sequencing

16-Lead SSOP Package

The LT3150’s transient load performance is optimized

with ceramic output capacitors. A precision 1.21V refer-

ence accommodates low voltage supplies.

APPLICATIO S

Protection includes a high side current limit amplifier that

activates a fault timer circuit. A multifunction shutdown

pin provides either current limit time-out with latchoff,

overvoltageprotectionorthermalshutdown. Independent

shutdown control of the boost converter provides on/off

and sequencing control of the LDO output voltage.
