TPS7A4501KTTR 1 Features 3 Description
The TPS7A45xx devices are low-dropout (LDO)
1• Optimized for Fast Transient Response
regulators optimized for fast transient response. The
TPS7A4501KTTR • Output Current: 1.5 A device can supply 1.5 A of output current with a
TPS7A4501KTTR • High Output Voltage Accuracy: 1% at 25°C dropout voltage of 300 mV. Operating quiescent
TPS7A4501KTTR • Dropout Voltage: 300 mV current is 1 mA, dropping to less than 1 μA in
shutdown. Quiescent current is well controlled; it does
• Low Noise: 35 μVRMS (10 Hz to 100 kHz) not rise in dropout as with many other regulators. In
• High Ripple Rejection: 68 dB at 1 kHz addition to fast transient response, the TPS7A45xx
(TPS7A4501 Only) addition of ESR as is common with other regulators.
• Less Than 1-μA Quiescent Current in Shutdown Internal protection circuitry includes reverse-battery
protection, current limiting, thermal limiting, and • Stable With 10-μF Ceramic Output Capacitor
reverse-current protection. The devices are available
• Reverse-Battery Protection in fixed output voltages of 1.5 V, 1.8 V, 2.5 V, 3.3 V,
• Reverse Current Protection and as an adjustable device with a 1.21-V reference
voltage.
