The PTH08080WAZ is a 1-output surface-mount non-isolated Step-down Switching Regulator that delivers up to 2.25A of output current. The PTH08080W sources output current at a much higher efficiency than a TO-220 linear regulator IC, thereby eliminating the need for a heat sink. Its small size (0.5 x 0.6-inch) and flexible operation creates value for a variety of applications. The input voltage range of the PTH08080W is from 4.5 to 18 V, allowing operation from either a 5 or 12V input bus. Using state-of-the-art switched-mode power-conversion technology, the PTH08080W can step down to voltages as low as 0.9V from a 5V input bus, with less than 1W of power dissipation. The output voltage can be adjusted to any voltage over the range 0.9 to 5.5V, using a single external resistor. Operating features include an under-voltage lockout (UVLO), on/off inhibit, over current protection and over temperature protection.
● Wide-output voltage adjust
● Efficiencies up to 93%
● ON/OFF inhibit
● Under-voltage lockout (UVLO)
● Output over current protection (non-latching, auto-reset)
● Over temperature protection
● -40 to 85°C Ambient temperature range
●IC can be damaged by ESD. We recommend that all ICs be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
