SBVS267A – JANUARY 2016 – REVISED FEBRUARY 2016 TPS7A85
High-Current (4 A), High-Accuracy (1%), Low-Noise (4.4 ВµVRMS), LDO Voltage Regulator
1 Features 3 Description The TPS7A85 is a low-noise (4.4 ВµVRMS), low-dropout
linear regulator (LDO) capable of sourcing 4 A with
only 240 mV of maximum dropout. The device output
voltage is pin-programmable from 0.8 V to 3.95 V and
adjustable from 0.8 V to 5.0 V using an external
resistor divider. 1 Low Dropout: 150 mV (typ) at 4 A
1% (max) Accuracy Over Line, Load, and
Temperature
Output Voltage Noise:
– 4.4 µVRMS at 0.8-V Output
– 8.4 µVRMS at 5.0-V Output
Input Voltage Range:
– Without BIAS: 1.4 V to 6.5 V
– With BIAS: 1.1 V to 6.5 V
