The LT3042HMSE#PBF belongs to PMIC (Power Management Integrated Circuit) Voltage Regulators category. It is a low quiescent current linear voltage regulator with enable. This device has a wide input and output voltage range with up to 40V input and output voltage adjustable range.

The LT3042HMSE#PBF application fields mainly include computing, communications, consumer electronics and industrial motors. The ultra-low quiescent current (100 uA) makes the LT3042HMSE#PBF suitable for computers, motor drives and precision instruments, such as wearable and handheld devices.

In terms of working principle, the LT3042HMSE#PBF features a precision reference combined with a current−limited error amplifier, series pass element and short-circuit protected Sink/Source Bypass architecture along with a shutdown control terminal. The voltage output ensured by the setting of two resistors provides an accuracy of ± 0.8%.

The LT3042HMSE#PBF has high-efficiency conversion performance, programmable short circuit protection (SSP) and pulse-skipping (PS) modes, as well as an enable input. The device provides fast load/line transient response and a high current-limiting capacitor. The built-in thermal shutdown ensures smooth operation even in high ambient temperatures and overload conditions, while the current limit protection acts as an overcurrent protection and prevents overload conditions. The device is also equipped with an over temperature protection feature, allowing the device to operate at maximum efficiency by reducing unnecessary heat output.

In conclusion, the LT3042HMSE#PBF is a low quiescent current, linear voltage regulator with enable that provides high-efficiency conversion performance, fast load/line transient response, programmable short circuit protection (SSP) and pulse-skipping (PS) modes, an enable input, and built-in thermal protection. It is suitable for computers, motor drives and precision instruments, such as wearable and handheld devices, in the computing, communications, consumer electronics and industrial motors fields.
