The TLV431IDBVRE4 is a voltage reference designed specifically for Power Management IC (PMIC) applications. It is a single-supply reference designed to provide precision output voltages over a wide operating-temperature and input-voltage range. The voltage reference features a low input current, low temperature coefficient, and low output-voltage drift. In PMIC applications, the TLV431IDBVRE4 is an ideal replacement for traditional two-terminal voltage references.

The TLV431IDBVRE4 is a bandgap based, single-supply voltage reference. Its two internal series voltage reference elements form a low-dropout voltage follower/voltage divider circuit. This class of voltage reference is characterized by very low input currents and low output voltages, typically in the range of 0.6V to 1.4V. It has a pre-programmed temperature coefficient of 2 ppm/C, and its tolerance is typically 1%.

The TLV431IDBVRE4 operates over a wide range of supply voltages between 2.2V and 10V with a typical supply current of 850uA. The output voltage is independent of the supply voltage, typically 0.1V higher than the setpoint volts. The low power consumption and high accuracy make the TLV431IDBVRE4 an ideal choice for battery-operated electronic devices. This reference is also designed to deliver an accurate output voltage over a wide temperature range, up to 150C.

In PMIC applications, the TLV431IDBVRE4 finds wide use for low dropout voltage references for current limit and shutdown circuits. The reference is used in other applications such as over-voltage protection circuits in battery powered systems, switches, pulse controllers, and other analog control circuits. The reference serves to maintain the desired voltage level for voltage control, memory retention, and current reference.

The TLV431IDBVRE4 is a precision, low-dropout voltage reference specifically designed for PMIC applications. It features an extremely low input current, a wide operating temperature range, and a low temperature coefficient. The reference is a bandgap-based single-supply voltage reference which creates a voltage follower circuit when installed. It offers excellent accuracy over a wide voltage and temperature range and is ideal for battery-operated electronic devices. The TLV431IDBVRE4 is commonly used in PMIC applications such as current limit, shutdown, and overvoltage protection circuits. Additionally, it finds wide use in analog control circuits such as switches, pulse controllers, and voltage control.
