TPS72301DBVR

200毫安低噪声，高PSRR负输出低压差线性稳压器 200 mA LOW NOISE HIGH PSRR NEGATIVE OUTPUT LOW DROPOUT LINEAR REGULATORS

DESCRIPON

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.
