TPS723
- Ultralow noise: 60 µVRMS typical
- High PSRR: 65 dB typical at 1 kHz
- Low dropout voltage: 280 mV typical at 200 mA, 2.5 V
- Available in –2.5-V and adjustable (–1.2 V to –10 V) versions
- 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
- Packages:
- SOT23-5 (DBV)
- SOT23-5 (DDC)
- WSON-6 (DRV)
- Operating junction temperature range: –40°C to 125°C
The TPS723 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 –10 V to –2.7 V, and support outputs from –10 V to –1.2 V. This 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 1 kHz) and low noise (60 µVRMS) make the TPS723 ideal for low-noise applications.
The TPS723 uses a precision voltage reference to achieve 2% overall accuracy over load, line, and temperature variations. Available in a small SOT23-5 package, the TPS723 is fully specified over a temperature range of –40°C to 125°C.
