Bypass VOUT to GND with a 1 μf or greater capacitor. 2 SENSE/ADJ Sense (SENSE). Measures the actual output voltage at the load and feeds it to the error amplifier. Connect SENSE as close as possible to the load to minimize the effect of IR drop between the regulator output and the load. This function applies to fixed voltages only. Adjust Input (ADJ). An external resistor divider sets the output voltage. This function applies to adjustable voltages only. 3 GND Ground. 4 NC Do Not Connect to this Pin. 5 EN/UVLO Enable Input (EN). Drive EN high to turn on the regulator; drive EN low to turn off the regulator. For automatic startup, connect EN to VIN. Programmable Undervoltage Lockout (UVLO). When the programmable UVLO function is used, the upper and lower thresholds are determined by the programming resistors. 6 GND Ground. 7 PG Power Good. This open-drain output requires an external pull-up resistor to VIN or VOUT. If the part is in shutdown, current limit, thermal shutdown, or falls below 9% of the nominal output voltage, PG immediately transitions low. If the power good function is not used, the pin may be left open or connected to ground. 8 VIN Regulator Input Supply. Bypass VIN to GND with a 1 μf or greater capacitor. EPAD Exposed Pad. Exposed paddle on the bottom of the package. The EPAD enhances thermal performance and is electrically connected to GND inside the package. It is highly recommended that the EPAD be connected to the ground plane on the board. Rev. D Page 6 of 28

17 Data Sheet THEORY OF OPERATION The ADP712 is a low quiescent current, low-dropout linear regulator that operates from 3.3 V to 2 V and provides up to 3 ma of output current. Drawing a low 75 μa of quiescent current (typical) at full load makes the ADP712 ideal for battery-operated portable equipment. Typical shutdown current consumption is 4 μa at room temperature. Optimized for use with small 1 μf ceramic capacitors, the ADP712 provides excellent transient performance.

Fixed Output Voltage Internal Block Diagram VREG 1µA SHORT-CIRCUIT, THERMAL PROTECT SHUTDOWN PGOOD 1.22V REFERENCE VOUT PG SENSE VOUT PG SENSE Figure 61. Adjustable Output Voltage Internal Block Diagram Internally, the ADP712 consists of a reference, an error amplifier, a feedback voltage divider, and a PMOS pass transistor. Output current is delivered via the PMOS pass device, which is controlled by the error amplifier. The error amplifier compares the reference voltage with the feedback voltage from the output and amplifies the difference. If the feedback voltage is lower than the reference voltage, the gate of the PMOS device is pulled lower, allowing more current to pass and increasing the output voltage. If the feedback voltage ADP712 is higher than the reference voltage, the gate of the PMOS device is pulled higher, allowing less current to pass and decreasing the output voltage. The ADP712 is available in 7 fixed output voltage options, ranging from 1.8 V to 9 V and in an adjustable version with an output voltage that can be set to between 1.22 V and 19 V by an external voltage divider. The output voltage can be set according to the following equation: VOUT = 1.22 V(1 + R1/R2) VIN = 8V OFF ON CIN 1µF R3 1kΩ R4 1kΩ + VIN VOUT R1 4.2kΩ ADJ EN/ UVLO GND PG R2 13kΩ RPG 1kΩ VOUT = 5V + COUT 1µF Figure 62. Typical Adjustable Output Voltage Application Schematic The value of R2 should be less than 2 kω to minimize errors in the output voltage caused by the ADJ pin input current. For example, when R1 and R2 each equal 2 kω, the output voltage is 2.44 V. The output voltage error introduced by the ADJ pin input current is 2 mv or.8%, assuming a typical ADJ pin input current of 1 na at 25 C. The ADP712 uses the EN/UVLO pin to enable and disable the VOUT pin under normal operating conditions. When EN/UVLO is high, VOUT turns on, when EN is low, VOUT turns off. For automatic startup, EN/UVLO can be tied to VIN. The ADP712 incorporates reverse current protections circuitry that prevents current flow backwards through the pass element when the output voltage is greater than the input voltage. A comparator senses the difference between the input and output voltages. When the difference between the input voltage and output voltage exceeds 55 mv, the body of the PFET is switched to VOUT and turned off or opened. In other words, the gate is connected to VOUT.
