The ADP2504ACPZ-4.2-R7 is a fully integrated DC to DC switching regulator from the PMIC line of adjustable voltage regulators and is used to deliver regulated output power from a finite DC source in a wide array of applications. The ADP2504ACPZ-4.2-R7 is a highly efficient, low dropout regulator that provides up to 4.2V of voltage regulation with a wide input voltage range of 4.5V to 23V. Designed to operate in both a variable current and variable voltage mode, the ADP2504ACPZ-4.2-R7 is ideal for applications that require high power efficiency and low noise operation.

The ADP2504ACPZ-4.2-R7 operates as a DC-DC buck regulator in variable voltage mode with a voltage range from 1.25V up to 4.2V. It also operates as a DC-DC buck-boost converter in variable current mode with a maximum current of 500mA. The output reachable in variable current mode is dependent upon the supply voltage and can reach up to the input voltage. The output load current is adjustable with the external resistor. The device also contains integrated short circuit, undervoltage, and overcurrent protection to protect the system in the event of any fault conditions.

The ADP2504ACPZ-4.2-R7 also features a programmable external synchronization option that allows the device to be synchronized with an external clock signal. This enables operation at different switching frequencies and can reduce switching noise and EMI. The device includes an enable control pin which can be used to enable or disable the device with an external signal. The ADP2504ACPZ-4.2-R7 also incorporates soft-start and trim pins for further regulation control and flexibility.

The ADP2504ACPZ-4.2-R7 is available in a tiny, three pad, 5-pin SOT23 transistor-outline package for applications with limited board space. The chip’s low resistance package, small size and low profile make it particularly useful for low voltage, portable systems, such as cellular phones and tablet computers. The device’s low profile and small size allow the voltage regulator to sit flush or be easily hidden away in a tiny space. The ADP2504ACPZ-4.2-R7 is environmentally friendly, uses very low power and will safely operate within a wide temperature range of -40C to +125C.

The ADP2504ACPZ-4.2-R7 is a versatile, low dropout voltage regulator that can be used in a variety of applications and can provide up to 4.2V of regulation. The device is highly efficient and can be used in both variable current and variable voltage modes with adjustable current and voltage output. It also features integrated protection, and an external synchronization option that allows the regulator to be synchronized with an external clock signal. The ADP2504ACPZ-4.2-R7 is available in a tiny, three pad, 5-pin SOT23 transistor-outline package and is suitable for applications with limited board space.
