The TPS767D301PWP is a Dual-output Low-dropout (LDO) Voltage Regulator that offers fast transient response, low dropout voltages, dual outputs and incorporating stability with 10µF low ESR output capacitors. The TPS767D301 dual voltage regulator is designed primarily for DSP applications. This device can be used in any mixed-output voltage application, with each regulator supporting up to 1A. Dual active-low reset signals allow resetting of core-logic and I/O separately. Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low and is directly proportional to the output current. Additionally, since the PMOS pass element is a voltage-driven device, the quiescent current is very low and independent of output loading (typically 85µA over the full range of output current, 0mA to 1A). These two key specifications yield a significant improvement in operating life for battery-powered systems.

The LM337IMP is a three terminal adjustable negative voltage regulator in 4 pin SOT-223 package. This regulator is exceptionally easy to apply and requires only two external resistors to set output voltage and one output capacitor for frequency compensation. The circuit design has been optimized for excellent regulation and low thermal transients. The LM137 features internal current limiting, thermal shut down and safe area compensation by making them virtually blowout proof against overloads. This positive voltage regulator is used in wide variety of applications including local on-card regulation, programmable output voltage regulation or precision current regulation.
