SC4216STRT Pinout Equivalent Circuit

1：Overview of the SC4216STRT:

SC4216STRT is a high-performance power regulator designed for applications that require very low input voltages and very low drop voltages (up to 3 amps). The operating voltage is 1.45V to 5.5V, the output voltage can be adjusted between 0.5V and 3.8V, and there are also fixed output Settings of 0.5V and 1.2V, depending on the configuration of the feedback pin. With ultra-low differential.The SC4216STRT provides excellent adjustment to changes in line, load and temperature. SC4216STRT is widely used in industry, telecommunications, medical, computer and other fields.

2：SC4216STRT Important pin function definition:

Pin	Pin Name	Pin Function
2	EN	Enable Input. Pulling this pin below 0.4V turns the regulator off, reducing the quiescent current to a fraction of its operating value. The device will be enabled if this pin is left open. Connect to VIN if not being used.
3	VIN	Input voltage. For regulation at full load, the input to this pin must be between (VO + 0.5V) and 5.5V. Minimum VIN = 1.45V. A large bulk capacitance should be placed closely to this pin to ensure that the input supply does not sag below 1.4V. Also a minimum of 4.7uF ceramic capacitor should be placed directly at this pin.
6	VO	The pin is the power output of the device. A minimum of 10uF capacitor should be placed directly at this pin.
7	FB	When this pin is grounded, an internal resistor divider sets the output voltage to 1.2V. If connected to the VO pin, the output voltage will be set at 0.5V. If external feedback resistors are used, the output voltage will be determined by the resistor ratio (See Application Circuits on page 1).
8	GND	Reference ground. The GND pin and the exposed die pad must be connected together at the IC pin.
1, 4, 5	NC	No Connection.
—	THERMAL PAD	Pad for heatsinking purposes. Connect to ground plane using multiple vias.

3.Partial circuit diagram of the SC4216STRT component.

The following is a typical application circuit diagram of SC4216STRT. ENABLE can set the working state of the chip and adjust the output voltage by setting the resistance values of R1 and R2

4：Alternative model recommendation

LT1763：

The LT1763 is a linear voltage regulator chip manufactured by Adno Semiconductor. With low pressure difference, can work stably when the input and output pressure difference is small, the output current ability is strong, and has good linearity and load regulation characteristics. The LT1763 has a wider input voltage and output range than the SC4216STRT, but the LT1763 has a weaker output current capability than the SC4216STRT. Both have an 8-SOIC package version, which has a certain degree of interchangeability in the package and is convenient for alternative use.

ADP1715：

The input voltage range of the ADP1715 is between 2.3V and 5.5V, and the output voltage can be adjusted between 0.8V and 3.6V, with a maximum output current of 1A. The output current of the ADP1715 is lower than that of the SC4216STRT, so attention should be paid when considering it as an alternative. The ADP1715 has fast transient response capabilities, allowing it to quickly respond to load changes and ensure stable output voltage. The ADP1715 is commonly used in battery-powered portable devices and IoT devices where power response speed and power consumption are critical requirements.

TPS74517：

The TPS74517 is a fixed-output linear regulator with an input voltage range of 2.2 V to 6.0 V, providing an output current of 500 mA. It is available in WSON-6 or MSOP-8 package options. Its input voltage range is wider than that of the SC4216STRT. Additionally, it features built-in soft start and power-good (PG) indicators, simplifying power sequencing management.
