Package drawings may show a different suffix character, but the drawing pertains to the package regardless of RoHS status.
Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board. For detailed information on package thermal considerations, refer to www.maximintegrated.com/thermal-tutorial.
Regulator Supply Input Pin. Connect to voltage between 1.7V and 5.5V, and bypass with a 4.7µF capacitor from IN to GND.Regulator Ground Pin. Bring IN and OUT bypass capacitor GND connections to this pin for best performance. Short the pin to EP in PCB layout in TDFN applications.Enable Input Pin. Connect this pin to a logic signal to enable (VEN high) or disable (VEN low) the regulator output. Connect to IN to keep the output enabled whenever a valid supply voltage is present.Mode-Select Pin. Connect this pin to a logic-high signal if normal operation is desired, and connect it to a logic-low signal if low-power operation is desired. When MODE is high, maximum output load current when LDO is in regulation is 500mA, and when MODE is low, maximum output load current is 20mA.Power-OK Output Pin. Connect a pullup resistor from this pin to a supply to create a signal that goes high after the regulator output has reached its regulation voltage.MAX38911: Output Voltage Sense Input. Connect to the load at a point where accurate regulation is required to eliminate voltage drops.MAX38912: Feedback Input Pin. Connect a resistor-divider string from OUT to GND with the midpoint tied to this pin to set the output voltage. In a typical application circuit, VOUT = 0.6V x (1 + RFBTOP/RFBBOT).Bypass Capacitor Input Pin. Connect a 0.001µF to 0.1µF capacitor between OUT and BYP to reduce output noise and set the regulator soft-start rate.Regulator Output Pin. Sources up to 500mA when MODE = HIGH and up to 20mA when MODE = LOW at the output regulation voltage. Bypass with a 4.7µF (2µF minimum effective capacitance), low-ESR (< 0.03Ω) capacitor to GND.Exposed Pad. Connect the exposed pad to a ground plane with low thermal resistance to provide best heat sinking. Connected to GND internally.
