TPS732
- Stable with no output capacitor or any value or type of capacitor
- Input voltage range: 1.7V to 5.5V
- Ultra-low dropout voltage: 40mV typical at 250mA
- Excellent load transient response—with or without optional output capacitor
- NMOS topology provides low reverse leakage current
- Low noise: 30µVRMS typical (10kHz to 100kHz)
- 0.5% initial accuracy
- 1% overall accuracy (line, load, and temperature)
- Less than 1µA maximum IQ in shutdown mode
- Thermal shutdown and specified min and max current limit protection
- Available in multiple output voltage versions:
- Fixed outputs of 1.2V to 5V
- Adjustable outputs from 1.2V to 5.5V
- Custom outputs available
The TPS732 low-dropout (LDO) voltage regulator uses an NMOS pass transistor in a voltage-follower configuration. This topology is stable using output capacitors with low equivalent series resistance (ESR), and even allows operation without a capacitor. The device also provides high reverse blockage (low reverse current) and ground pin current that is nearly constant over all values of output current.
The TPS732 uses an advanced BiCMOS process to yield high precision while delivering very low dropout voltages and low ground pin current. Current consumption, when not enabled, is less than 1µA and designed for portable applications. The extremely low output noise (30µVRMS with 0.1µF CNR) is designed for powering VCOs. This device is protected by thermal shutdown and foldback current limit.
