3 / 12 page ST2L01 3/12 TYPICAL APPLICATION CIRCUIT Note: CO1 value could be lowered down to 470nF Ceramic Capacitor (X7R); CI, CO1 and CO2 capacitors must be located not more than 0.5" from the outputs pins of the device. For more details about Capacitors read the "Application Hints" ELECTRICAL CHARACTERISTICS OF OUTPUT 1 (VI=5V, IO1=10mA Tj = 0 to 125°C unless otherwise specified. Typical values are referred at Tj = 25°C, CI = 1µF (Tantalum), CO1 = CO1 =1µF (X7R) Note 1: Low duty cycle pulse testing with Kelvin connections are required in order to maintain accurate data Note 2: Dropout Voltage is defined as the minimum differential voltage between VI and VO required to mantain regulation at VO. It is measured when the output voltage drops 1% below its nominal value. Note 3: Transient response is defined with a step change in load from 10mA to 500mA as the time from the load step until the output voltage reaches it’s minimum value. Note 4: Minimum load current is defined as the minimum current required at the output in order for the output voltage to maintain regulation. Note 5: Guaranteed by design, not tested in production.
