DESCRIPTION

The TPS723xx-Q1 family of low-dropout (LDO)

negative voltage regulator offers an ideal combination

of features to support low noise applications. This

device is capable of operating with input voltages

from –10V to –2.7V. The TPS72325-Q1 regulator is

stable with small, low-cost ceramic capacitors, and

include enable (EN) and noise reduction (NR)

functions. Thermal short-circuit and over-current

protections are provided by internal detection and

shutdown logic. High PSRR (65 dB at 1kHz) and low

noise (60μV_RMS) make the TPS723xx-Q1 ideal for

low-noise applications.

•

Stable With a 2.2 μF Ceramic Output Capacitor

Less Than 2 μA Typical Quiescent Current in

Shutdown Mode

•

2% Overall Accuracy

(Line, Load, Temperature)

•

Thermal and Over-Current Protection

SOT23-5 (DBV) Package

Operating Junction Temperature Range: –40°C

to 125°C

The TPS723xx-Q1 uses a precision voltage reference

to achieve 2% overall accuracy over load, line, and

temperature variations. Available in a small SOT23-5

package, the TPS723xx-Q1 is fully specified over a

temperature range of –40°C to +125°C.
