TPS78915DBVR

The TPS78915DBVR is a linear low-dropout (LDO) voltage regulator, designed primarily for point-of-load (POL) applications in consumer and industrial equipment. It is a voltage regulator that provides high performance and low power consumption while allowing the user to maintain accurate voltage regulation within a wide operating temperature range.

The TPS78915DBVR can supply up to 50mA of continuous current and up to 150mA of peak current to the load. It features a wide input voltage range of 2.5V to 5.5V and an adjustable output voltage range of 0.8V to 4.1V. It has an ultra-low dropout voltage of 200 mV at full load and excellent ±2% output voltage accuracy across the temperature range from -40°C to 85°C.

The TPS78915DBVR features programmable output voltage options, allowing the part to be used in places where a specific voltage is needed. This feature also serves to protect the device from catastrophic events, and enable safe shutdown in case of input voltage drops. The device has an enable/disable pin, so power can be shut down when no load current is present.

The TPS78915DBVR supports low-current sleep mode, which helps conserve power when the device is inactive. In addition, it has an integrated over-temperature protection (OTP) feature which prevents overheating. This feature is enabled by an external thermistor placed on the PCB, which monitors the temperature of the device and turns off the regulator if it exceeds the pre-set threshold. This helps ensure that the system is not damaged due to excessive temperatures.

The TPS78915DBVR is highly efficient and stable. It offers current-mode control and peak currents up to 1.2A which helps it stay stable at high operating frequencies. The device is capable of delivering very low output voltage noise levels as low as 17 µVrms/Hz, with excellent transient response and start-up behavior.

The TPS78915DBVR is ideal for use in a wide variety of point-of-load applications, such as digital cameras, hand-held devices, and portable battery-powered equipment. It is highly durable and resistant to vibrations, making it ideal for use in industrial equipment. In addition, its wide temperature range allows it to be used in aggressive thermal environments. The TPS78915DBVR has passed safety approvals, making it applicable for a wide range of international markets.
