AS13985F29-T is a CMOS low dropout (LDO) linear voltage regulator. It is a low-cost, low-noise linear voltage regulator that maintains a stable output voltage despite fluctuations in supply voltage or changes in load current. It is designed to provide a regulated output voltage (2.5V, 3.3V, 5V, 6V, 8V, 10V, 12V). The device features excellent line and load transient response, low output noise, and fast turn-on/turn-off times. In addition, AS13985F29-T has a number of protection features including over-current, over-voltage, and thermal protection.
Application Field
AS13985F29-T is designed to provide a regulated output voltage over a wide range of operating conditions. It is suitable for a wide range of applications such as notebook computers, PDAs, mobile phones, digital cameras, home appliances, industrial controllers, and automotive applications. It is also suitable for powering other electronic components such as FPGAs, ASICs, DSPs, and other sensitive analog circuits. It is especially well-suited for applications where low noise and tight output regulation are required.
Working Principle
The AS13985F29-T uses a p-channel MOSFET as the pass transistor to regulate the output voltage. The output voltage is set using an external voltage divider connected to the adjustment pin. The control circuitry within the device monitors the output voltage, and adjusts the gate voltage of the pass transistor in order to maintain the required output voltage. To prevent negative transients, an internal soft-start voltage limiting circuit is included in the device. This circuit limits the inrush current when the device is first turned on, reducing the risk of inrush-related damage to the device.
In order to protect the device from over-current and over-voltage conditions, AS13985F29-T includes several protection features. When an over-current condition is detected, the device switches off the pass transistor and a flag is set indicating the fault. An over-voltage protection feature ensures that the output voltage does not exceed the set limit. Additionally, the device includes an over-temperature protection feature which switches off the pass transistor when the die temperature exceeds a set level. This ensures that the device is protected from excessive heat and will not be damaged when operating in an environment with high ambient temperatures.
AS13985F29-T is an efficient linear voltage regulator with excellent line and load regulation. It is designed to provide a regulated output voltage in a wide range of applications, and features protection against over-current, over-voltage, and over-temperature conditions. It is suitable for powering a variety of electronic components and is particularly well-suited for applications that require low noise and tight output regulation.
