The LM2936HVMA-5.0 is a high voltage fixed output, low dropout (LDO) linear voltage regulator that offers both high efficiency and high voltage regulation. It is intended for the application of power-supply regulation in applications ranging from consumer electronics to automotive. This regulator has a wide input range of 4.75 to 40 V, making it well suited for automotive applications; the maximum output voltage is 5 V. This particular part is particularly well-suited for automotive applications as it boasts a low quiescent current, SOI technology, fast transient response time, and ESD protection.

The LM2936HVMA-5.0 is a monolithic regulator that offers a regulated output voltage via an internal series pass regulator. In contrast to other linear regulators, the LM2936HVMA-5.0 uses the voltage drop across an internal PNP pass transistor to regulate its output voltage. With its precision voltage reference, the device can easily maintain an output voltage tolerance within 0.4% over line, load and temperature variations.

The high efficiency comes from the low dropout feature. By utilizing the efficient dropout voltage, the LM2936HVMA-5.0 can maintain an input-output differential as low as 0.6V, which is much lower than that of traditional linear regulators. This allows the device to dissipate less power, thus achieving better efficiency and thereby minimizing heat generation.

The LM2936HVMA-5.0 includes built-in protection features such as short-circuit protection and thermal shutdown. Its unique design also allows the device to be operated within a wide temperature range (-40°C to +85°C). The device has a quiescent current of only 40 microamperes and a low voltage drop of 0.6V, making it ideal for portable battery-powered applications.

The LM2936HVMA-5.0 is a cost-effective and efficient device for power-supply solutions with high voltage and current requirements. The device meets the needs of applications from consumer electronics to automotive, and is suitable for both linear and switch-mode power supplies. With its high efficiency, low quiescent current, low voltage drop, and wide input and output range, the LM2936HVMA-5.0 is an ideal solution for all types of power-supply applications.
