The MAX635AESA+ is a high-efficiency, low drop-out (LDO) voltage regulator designed to power portable electronics with a wide range of input voltage characteristics. The device can operate at input voltages of up to 7V and deliver output current up to 2mA. This device is lightweight and small in size making it ideal for applications such as MP3 players and PDAs.

The MAX635AESA+ is a DC/DC switching regulator designed to control on-board and off-board power levels in portable applications. The device features a low voltage dropout (LDO) regulator design that allows it to regulate currents in both low current and high current (>2mA) without introducing affecting the total power delivered to the load. The MAX635AESA+ is a dual stage voltage regulator, providing both primary and secondary current regulation.

The primary stage is a fully integrated high efficiency buck-boost regulator that provides both high current (<2mA) and low current (<1mA) regulation from a wide range of input voltages. This stage is capable of operating from input voltages ranging from 3.1V to 7.5V and provides an output current up to 2mA.

The secondary stage is a high current, low dropout regulator that is capable of delivering output current up to 30mA. The MAX635AESA+ can be used to regulate both on-board and off-board power sources.

The MAX635AESA+ is designed with a hysteresis loop control structure that operates at high frequency. The hysteresis loop makes it possible to regulate the output voltage with no load to full load changes. This results in improved efficiency and superior line and load regulation.

The MAX635AESA+ consists of an internal voltage reference that limits the voltage output at the point of highest heavy-load consumption. The device has been designed to remain within a defined temperature range thanks to its thermal protection circuit.

The MAX635AESA+ can be used in a wide range of valuable applications, from MP3 players and PDAs to flash memory applications. In addition, it is excellent for use in consumer electronics where efficiency is an important factor. The device is also used in automotive applications that require low quiescent current.
