Description

TheZLDO270 Series low dropout linear regulators operate with an exceptionally low dropout voltage, typically only 30mV with a load current of 100mA. The regulator series features output voltages in the range 2.70 to 12 volts, this ZLDO270 provides an output voltage of 2.70 volts.

The ZLDO270 consumes a typical quiescent current of only 1mA at its maximum rated output current of 300mA. A battery low flag is available to indicate potential power fail situations. If the input voltage falls to within 200mV of the regulated output voltage then the error output pulls low. The ZLDO270 also features an active high disable control. Once disabled the ZLDO quiescent current falls to typically 11mA.

The ZLDO270 devices are packaged in Zetex SM8 8 pin small outline surface mount package, ideal for applications where space saving is important. The ZLDO270 low dropout voltage, low quiescent current and small size make it ideal for low power and battery powered applications. Battery powered circuits can make particular use of the low battery flag and shutdown features.
