LTC2938HDE#PBF

The LTC2938HDE#PBF is an integrated low-dropout linear voltage regulator from Linear Technology Corporation. This device belongs to the PMIC (Power Supply Controllers, Monitors) family and is specifically designed for use as a voltage regulator in portable and embedded systems. This voltage regulator combines a reference voltage, an error amplifier, a high-efficiency current limit and temperature protection circuits into a single package. It is highly integrated and can be used for applications such as cell phones, notebooks, Set-top boxes, and more. The device works by comparing the reference voltage to the input voltage and then using an internal error amplifier to adjust the output voltage accordingly. In order to ensure that the output voltage is maintained over a wide range of input voltages and temperatures, the device also employs a hysteretic current limit and various temperature protection circuits.

The LTC2938HDE#PBF can operate with a range of input voltages from 2.2V to 5.5V and is capable of delivering up to 1A of continuous output current with a precision of ±5% over a temperature range of -40°C to +125°C. It also features programmable delay time, soft start and power good outputs. This device features low current consumption of 2.5mA (typical). The device also offers a wide array of protection features, such as over-voltage, over-current and thermal protection. The device comes in a small 10-pin DFN package, which makes it easy to use in space-constrained applications.

The LTC2938HDE#PBF is a highly integrated one-chip power solution for embedded applications with stringent size and efficiency constraints. This device has several unique features that make it suitable for such systems, including its low quiescent current, high efficiency, wide operational temperature range, and comprehensive protection features. It is an ideal solution for applications where space is a premium, such as cell phones, notebooks, Set-top boxes, and other embedded systems.

In conclusion, the LTC2938HDE#PBF is a highly integrated voltage regulator that combines a reference voltage and an error amplifier with other features. It is designed for use in embedded applications and features low current consumption, high efficiency, wide operational temperature range and comprehensive protection features. It is an ideal solution for applications where space is a premium or are subject to thermal variation, such as cell phones, notebooks, Set-top boxes, and other embedded systems.
