LOW-NOISE, FAST-TRANSIENT-RESPONSE 1.5-A LDO VOLTAGE REGULATORS

FEATURES  
DESCRIPTION  
2
Optimized for Fast Transient Response  
Output Current: 1.5 A  
The TPS7A45xx devices are low-dropout (LDO)  
regulators optimized for fast transient response. The  
device can supply 1.5 A of output current with a  
dropout voltage of 300 mV. Operating quiescent  
current is 1 mA, dropping to less than 1 µA in  
shutdown. Quiescent current is well controlled; it does  
not rise in dropout, as with many other regulators. In  
addition to fast transient response, the TPS7A45xx  
regulators have very low output noise, which makes  
them ideal for sensitive RF supply applications.  
High Output Voltage Accuracy : 1% at 25°C  
Dropout Voltage: 300 mV  
Low Noise: 35 µVRMS (10 Hz to 100 kHz)  
High Ripple Rejection: 68 dB  
1-mA Quiescent Current  
No Protection Diodes Needed  
Controlled Quiescent Current in Dropout  
Fixed Output Voltages: 1.5 V, 1.8 V, 2.5 V, 3.3 V  
Adjustable Output from 1.21 V to 20 V  
<1-µA Quiescent Current in Shutdown  
Stable with 10-µF Output Capacitor  
Stable with Ceramic Capacitors  
Reverse-Battery Protection  
Output voltage range is from 1.21 V to 20 V. The  
TPS7A45xx regulators are stable with output  
capacitors as low as 10 µF. Small ceramic capacitors  
can be used without the necessary addition of ESR,  
as is common with other regulators. Internal  
protection  
circuitry  
includes  
reverse-battery  
protection, current limiting, thermal limiting, and  
reverse-current protection. The devices are available  
in fixed output voltages of 1.5 V, 1.8 V, 2.5 V, 3.3 V,  
and as an adjustable device with a 1.21-V reference  
voltage. The TPS7A45xx regulators are available in  
the 5-pin TO-263 (KTT) package.  
No Reverse Current
