ST1L02xx

Very low quiescent BiCMOS voltage regulator

Features

■ Fixed output voltage: 1.8 V, 2.5 V, 3.3 V (1.5 V,

under customer request)

■ Output voltage tolerance: 2 ꢀ at 25 °C

■ Output current capability: 1 A minimum

■ Very low quiescent current: max 500 µA over

DFN6D (3x3 mm)

temperature range

■ Typ. dropout 0.7 V (@ I = 1 A)

■ Stable with low ESR ceramic capacitors

Internal protection circuitry includes thermal

protection with hysteresis and over current

limiting.

■ Available with and without the external output

voltage sense pin

■ Thermal shutdown protection with hysteresis

■ Over current protection

The ST1L02xx is especially suitable for data

storage applications such as HDDs, where can be

used to supply the read channel and memory

chips requiring 3.3 V.

■ Operating junction temperature range:

from 0 to 125 °C

The regulator is available in the small and thin

DFN6D (3x3 mm) package.

Description

The ST1L02xx is a low drop linear voltage

regulator capable to supply up to 1 A output

current.

The output voltage is fixed to 3.3 V, but under

customer request, it’s possible to have also 1.5 V,

1.8 V and 2.5 V. Thanks to the BiCMOS

technology, the quiescent current is well

controlled and maintained below 650 µA over the

whole allowed junction temperature range.

The ST1L02xx is stable with low ESR output

ceramic capacitors.
