DESCRIPTION

Available in −2.5 V, and Adjustable

(−1.2 V to −10 V) Versions

The TPS723xx family of low-dropout (LDO) negative

voltage regulators offers an ideal combination of features

to support low noise applications. The devices are capable

of operating with input voltages from −10 V to −2.7 V, and

supporting outputs from −10 V to −1.2 V. These regulators

are 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 1 k Hz) and low noise (60 µV_RMS) make

the TPS723xx ideal for low-noise applications.

Stable With a 2.2-µF Ceramic Output

Thermal and Overcurrent Protection

5-Pin SOT-23 (DBV) Package

The TPS723xx 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 family is fully specified over a

temperature range of −40°C to 125°C.
