FEATURES

DESCRIPTION

The TPS734xx-Q1 family of low-dropout (LDO),

•

Qualified for Automotive Applications

250mA Low Dropout Regulator with EN

Low I_Q: 44μA

low-power linear regulators offers excellent ac

performance with very low ground current. High

power-supply rejection ratio (PSRR), low noise, fast

start-up, and excellent line and load transient

response are provided while consuming a very low

44μA (typical) ground current. The TPS734xx-Q1 is

stable with ceramic capacitors and uses an advanced

BiCMOS fabrication process to yield a typical dropout

voltage of 125mV at 250mA output. The

TPS734xx-Q1 uses a precision voltage reference and

feedback loop to achieve overall accuracy of 2% over

all load, line, process, and temperature variations. It

is fully specified from T_A= –40°C to +105°C and is

offered in a low-profile ThinSOT-23 package that are

ideal for wireless handsets, printers, and WLAN

cards.

Multiple Output Voltage Versions Available:

–

Fixed 3.3V Outputs

Adjustable Outputs from 1.25V to 6.2V

•

High PSRR: 60dB at 1kHz

Ultra-Low Noise: 28μV_RMS

Fast Start-Up Time: 45μs

Stable with a Low-ESR, 2.0μF Typical Output

Capacitance

•

Excellent Load/Line Transient Response

2% Overall Accuracy (Load/Line/Temp)
