LP2985AIBP-4.0 is a widely used linear voltage regulator from Texas Instruments’ family of Low Voltage Linear Regulators (LVLRs). This device is a low dropout (LDO) regulator with a minimum output voltage of 4 V and a maximum input voltage of 20 V. It is designed for low-noise, low-cost power supply applications such as powering audio circuits or low-power System on Chip (SoC) designs. Its integrated reverse-battery protection feature helps protect the device against over-voltage fault conditions by preventing reverse current flow.

The LP2985AIBP-4.0 is suitable for a wide variety of applications, ranging from industrial motor control, medical equipment, and personal computing to consumer electronics and automotive applications. The device can be used to provide power supply sequencing and fault protection for microcontrollers, DSPs and other sensitive logic circuits. It is also well suited for interface and power control circuits, including power sequencing, fault protection, and thermal regulation of digital subsystems. Its low quiescent current and low dropout voltage make the LP2985AIBP-4.0 a cost-effective and space-saving solution for these types of applications.

The LP2985AIBP-4.0 is designed to deliver regulated current over a wide input range while maintaining stable output voltages. It uses an accurate voltage reference with internal feedback loop, as well as high-precision load regulation circuitry, to ensure its performance. The device can deliver up to 1.5A of load current, making it suitable for loads with moderate current requirements. It has a wide operating temperature range of -40°C to +125°C, making it well suited for space-constrained applications, such as those in automotive and industrial environments.

The LP2985AIBP-4.0 is a highly reliable regulator with a PSRR (power supply rejection ratio) of 60 dB and low 1.5 μA quiescent current to minimize power consumption in standby mode. It features a short-circuit protection circuit and overvoltage protection, which can help to guard against sudden power surges or shorts. It also has an active-low shutdown pin that can be used to reduce overall system power consumption in standby and/or low power modes. In addition, the device is equipped with an integrated power-on reset circuit, which is used to reset the device and return it to a known state during startup. The reset signal is active during powerup, standby, and shutdown conditions.

The LP2985AIBP-4.0 is designed to provide protection against input overvoltage and output overcurrent conditions. When the input voltage exceeds the device’s absolute maximum voltage rating, the undervoltage lockout (UVLO) circuitry prevents the device from operating and driving any load current. When the output current exceeds the device’s maximum output current limit, the overcurrent protection (OCP) circuitry shuts down the device and engages the output shutoff circuit, preventing further current flow and eliminating the potential for damage. The LP2985AIBP-4.0 also features a thermal shutdown circuit that activates when the device’s junction temperature exceeds a certain limit, ensuring the device is not damaged by excessive heat.

Overall, the LP2985AIBP-4.0 is a highly efficient, accurate, and reliable voltage regulator specifically designed for use in low-cost, low-noise, and low-power applications. It is a cost-effective solution for systems that need to maintain a stable output voltage with changing input voltage and load conditions. Its wide input voltage range, low power consumption, and integrated protection circuits make it an ideal choice for space-constrained and low-cost applications.
