500mA Low-Noise LDO Voltage Regulator

August 2016

Rev. 2.0.3

GENERAL DESCRIPTION

APPLICATIONS

The SPX3819 is a positive voltage regulator

with a low dropout voltage and low noise

output. In addition, this device offers a very low

ground current of 800μA at 100mA output. The

SPX3819 has an initial tolerance of less than

1% max and a logic compatible ON/OFF

• Portable Consumer Equipment

• Portable Instrumentation

• Industrial Equipment

• SMPS Post Regulators

switched

input.

When

disabled,

power

consumption drops to nearly zero. Other key

features include reverse battery protection,

current limit, and thermal shutdown. The

SPX3819 includes a reference bypass pin for

optimal low noise output performance. With its

very low output temperature coefficient, this

device also makes a superior low power voltage

reference.

FEATURES

• Low Noise: 40μV Possible

• High Accuracy: 1%

• Reverse Battery Protection

• Low Dropout: 340mV at Full Load

• Low Quiescent Current: 90μA

• Zero Off-Mode Current

The SPX3819 is an excellent choice for use in

battery-powered applications such as cordless

telephones, radio control systems, and portable

computers. It is available in several fixed

output voltage options or with an adjustable

output voltage.

• Fixed & Adjustable Output Voltages:

− 1.2V, 1.5V, 1.8V, 2.5V, 3.0V, 3.3V & 5.0V

Fixed Output Voltages

− ≥1.235V Adjustable Output Voltages

This device is offered in 8 pin NSOIC, 8 pin DFN

and 5-pin SOT-23 packages.

• Available in RoHS Compliant, Lead Free

Packages:

− 5-pin SOT-23, 8-pin SOIC and 8-pin DFN
