500mA Peak, Thermal Folded Back CMOS LDO Regulator
General Description
The RT9017 is designed for portable RF and wireless
applications with demanding performance and space
requirements. The RT9017 performance is optimized for
battery-powered systems to deliver ultra low noise and
low quiescent current. Regulator ground current increases
only slightly in dropout, further prolonging the battery life.
The RT9017 also works with low-ESR ceramic capacitors,
reducing the amount of board space necessary for power
applications, critical in hand-held wireless devices. The
RT9017 consumes less than 0.01
μ
A in shutdown mode
and has fast turn-on time less than 50
μ
s. RT9017 is short
circuit thermal folded back protected. RT9017 lowers its
OTP trip point from 165
°
C to 110
°
C
when output short
circuit occurs (V
OUT
< 0.4V) providing maximum safety to
end users. The other features include ultra low dropout
voltage, high output accuracy, current limiting protection,
and high ripple rejection ratio. Available in the SOT-23-3,
SOT-23-5 and WDFN-6L 2x2 packages, the RT9017 also
offers a range of 1.5V t
o 3.5V
with 0.1V per step.
