TLV1117-33IDCYR 3.3V is a positive low-dropout voltage regulator on the Antminer S19 series hash board, which can provide up to 800mA output current. The device is available in 3.3V and adjustable output voltage options. All internal circuitry is designed to operate down to 1V input-to-output differential. Dropout voltage is specified at 1.3 V maximum at 800 mA and derates at lower load currents.
