TPS72301 200mA 低噪声、高 PSRR 负输出、低压降线性稳压器
TPS72301 描述
The TPS723xx family of low-dropout (LDO) negative voltage regulators offers an ideal combination of features to support low noise applications. These devices are capable of operating with input voltages from -10V to -2.7V, and support outputs from -10V to -1.2V. 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 (65dB at 1kHz) and low noise (60µVRMS) make the TPS723xx ideal for low-noise applications.
The TPS723xx uses a precision voltage reference to achieve 2% overall accuracy over load, line, and temperature variations.
