Principio de funcionamiento<\/h2>\n

An internal bandgap reference maintains 1.25V between VOUT and ADJ pins. External resistor divider from VOUT to ADJ to GND sets the output voltage: VOUT = 1.25V \u00d7 (1 + R2\/R1). The ADJ pin draws only ~50 \u00b5A, enabling accurate setting with standard resistors. Current limit (~200 mA) and thermal shutdown protect the device.<\/p>\n
