The NCP707CMX185TCG is a linear voltage regulator from ON Semiconductor which comes in a variety of package options. It is a suitable solution for providing a regulated, low-output voltage from an input voltage supply. The maximum output current is up to 1.5A and the maximum power supply rejection ratio is 90dB.

The NCP707CMX185TCG is specifically designed for providing a regulated output of -1.85V and stores the output voltage in a 0.2% tolerance, with a temperature coefficient of only 0.05%/°C. The linear voltage regulators work by dissipating power to maintain the constant output in spite of fluctuations in the supply voltage and supply current. The NCP707CMX185TCG supports a typical efficiency of up to 91%.

The input voltage range of the NCP707CMX185TCG is from 2.6V to 24V, while the dropout voltage is 200mV which is the difference between the input and output voltages. This IC configuration can provide up to 1.5A output current with a typical quiescent current of only 4mA. The NCP707CMX185TCG displays good thermal and process stability, that helps to prevent noise or jitter for clean and correct operations.

The NCP707CMX185TCG linear voltage regulator features a high Shunt Regulator Mode (SRM) where the current is by-passed from the output to the ground when the output reaches 1.875V. Thanks to this feature, the regulator works with an enhanced maximum load current capability of up to 30mA, compared to the 14mA current capability in conventional designs. This SRM is enabled by the EN function pin.

The output short circuit protection (SCP) and over temperature protection (OTP) of the NCP707CMX185TCG provides a safe operation and protection to the interface circuit components which are connected to the device. The over temperature protection of the device will shut off the output when the device temperature reaches 150°C.

The NCP707CMX185TCG is available in packages of two forms: either in 3 pin SC92 or in 4 pin SOT-23 package. Both packages allow easy mounting and connection to the circuit board.

The NCP707CMX185TCG linear voltage regulators are primarily used in applications where the output voltage needs to be held constant with respect to the input supply. These can be used in compact systems where the size of the device is limited due to space constraints. As an example, the device is extensively used in laptop computers, cellular phones, and other battery-powered electronic devices.

In conclusion, the NCP707CMX185TCG linear voltage regulator from ON Semiconductor is a suitable device for applications such as laptop computers, cellular phones, and other portable devices. The device featured a regulated output of -1.85V with a precision of 0.2%, a maximum output current of up to 1.5A, and high temperature stability. The device also has a high Shunt Regulator Mode (SRM) which provides a maximum load current of up to 30mA, and an output short circuit protection (SCP) and over temperature protection (OTP) for a safe operation.
