New Dual LDO with High PSRR and Low Quiescent Current from Diodes Incorporated is Aimed at Primary Cell Applications
March 29 2019 - 12:00PM
Business Wire
Diodes Incorporated (Nasdaq: DIOD), a leading global
manufacturer and supplier of high-quality application specific
standard products within the broad discrete, logic, analog and
mixed-signal semiconductor markets, today announced the AP7345D
family of dual low-dropout (LDO) voltage regulators that offer high
power supply rejection ratio (PSRR) and low quiescent current,
making them suitable for applications powered by primary cells such
as AA or AAA batteries.
The AP7345D offers independent voltage input with an enable pin
for controlling the output. This provides for more flexibility when
designing the power source for applications. Each channel switches
off or on within approximately 10µs of the EN pin changing state,
while the EN pin on each channel can also be tied high if output
control is not required.
The AP7345D family features an excellent PSRR of 75dB at 1kHz,
across the full output voltage range. The input voltage range
extends from 1.7V to 5.25V and each of the two channels can deliver
up to 300mA, guaranteed. The inclusion of short-circuit protection
ensures the LDO does not sustain damage in the event of a short
circuit on either of the output voltage rails.
The family comprises 22 devices covering a range of fixed
dual-input/dual-output voltages between 1.2V and 3.6V, with an
accuracy of ±1%. With such a comprehensive range, the AP7345D
family can address a wide variety of battery-powered applications.
The addition of an LDO enables more of the primary cells’ voltage
to be used, extending the useful lifetime between battery changes.
In addition, choosing an LDO with high PSRR ensures a steady and
regulated supply voltage to sensitive integrated circuits.
The AP7345D is packaged in X2-DFN1612-8 package, providing a
small PCB footprint to enable high levels of power density. Further
