LP2996AMRE/NOPB is a cost-efficient, low-noise, low-dropout (LDO) voltage regulator which provides a wide input voltage range and adjustable output voltage from 1.2V to 5.0V. It is specially designed for advanced portable equipment applications. This device is the first product available in the market that combines the features of low current consumption and dual output capability in a very small package, making it an ideal choice for regulated power supply applications.

The LP2996AMRE/NOPB features an enhanced transient response and an ultra-low operating current of only 1.0µA from a 3V supply. It is capable of supplying up to two separate supplies, which can be set independently. For cost efficiency, it requires few external components and eliminates the need for a expensive soft-start circuit. It is specifically designed to protect the device’s sensitive circuitry and components against the harmful effects of overvoltage and overcurrent by including voltage and current limiting protection.

The operating principle of the LP2996AMRE/NOPB is based on a standard linear amplifier with a differential input stage and voltage feedback. The device operates in two modes: active mode and Standby mode. In active mode, the device receives a regulated input voltage that is applied to the voltage reference block. This voltage is compared with a voltage reference, and the amplifier output is adjusted accordingly until the output voltage is equal to the reference voltage. In Standby mode, the amplifier adjusts the output voltage according to the load current. This provides a high degree of regulation accuracy to ensure no observed difference in voltage between the load and the power supply.

The LP2996AMRE/NOPB has many applications, including mobile phones and other portable equipment, as well as in AC adapters, battery charging, USB ports, embedded systems, industrial and automotive electronics, digital clocks, and disk drives. It can also be employed to regulates the output of a wide variety of electronic devices and circuits. This device is cost-efficient, requires few external components, and has a wide input voltage range.
