LT3029

Dual 500mA/500mA

Low Dropout, Low Noise,

Micropower Linear Regulator

DescripTion

FeaTures

The LT^®3029 is a dual, micropower, low noise, low drop-

out linear regulator. The device operates either with a

common input supply or independent input supplies for

each channel, over an input voltage range of 1.8V to 20V.

Each output supplies up to 500mA of output current with

a typical dropout voltage of 300mV. Quiescent current is

well controlled in dropout. With an external 10nF bypass

Output Current: 500mA per Channel

Low Dropout Voltage: 300mV

Low Noise: 20µV

(10Hz to 100kHz)

RMS

Low Quiescent Current: 55µA per Channel

Wide Input Voltage Range: 1.8V to 20V (Common or

Independent Input Supply)

Adjustable Output: 1.215V Reference Voltage

Very Low Quiescent Current in Shutdown: <1µA per

Channel

Stable with 3.3µF Minimum Output Capacitor

Stable with Ceramic, Tantalum or Aluminum

Electrolytic Capacitors

Reverse-Battery and Reverse Output-to-Input

Protection

Current Limit with Foldback and Thermal Shutdown

Tracking/Sequencing Capability: Compatible with

capacitor, output noise is only 20µV

over a 10Hz to

RMS

100kHz bandwidth. Designed for use in battery-powered

systems, the low 55µA quiescent current per channel

makes it an ideal choice. In shutdown, quiescent current

drops to less than 1µA. Shutdown control is independent

foreachchannel,allowingforﬂexiblepowermanagement.

TheLT3029optimizesstabilityandtransientresponsewith

low ESR ceramic output capacitors, requiring a minimum

of only 3.3µF. The regulator does not require the addition

of ESR, as is common with other regulators.

Internal circuitry provides reverse-battery protection,

reverse-current protection, current limiting with foldback

and thermal shutdown. The device is available as an

adjustable output voltage device with a 1.215V reference

voltage. The LT3029 is offered in the thermally enhanced

16-lead MSOP and 16-lead, low proﬁle (4mm × 3mm ×

0.75mm) DFN packages.
