Automotive-Compliant Linear Regulators from Diodes Incorporated Deliver High PSRR and Low Quiescent Current
October 09 2019 - 6:16PM
Business Wire
Diodes Incorporated (Nasdaq: DIOD) today introduced the
company’s first low-dropout (LDO) linear regulators compliant to
AEC-Q100 Grade 1. The AP7315Q and AP7343Q deliver 150mA and 300mA
respectively and are suitable for any automotive application that
requires tight voltage regulation across operating conditions, such
as point-of-load power supplies in advanced driver assist systems
(ADAS), RF communications, infotainment systems, and cameras.
Automotive manufacturers are integrating an increasing level of
ADAS into vehicles with sensors and other sensitive circuits that
demand highly stable power supplies. With full production part
approval process (PPAP) capability, the AP7315Q and AP7343Q linear
regulators can be used in automotive applications that require
product qualified to AEC-Q100 with a Grade 1 (-40°C to +125°C)
temperature rating.
The AP7315Q and AP7343Q provide practical alternatives to
switching regulators in highly demanding automotive applications.
As well as current limiting and short-circuit protection, the LDOs
feature an enable input that allows the linear regulators to be
switched off when not required. While in use, the regulators have a
low quiescent current of just 35μA. Both devices are also available
with (AP7315DQ/43DQ) and without (AP7315Q/43Q), an output capacitor
discharge feature, which is often required to protect sensitive
loads during shutdown, such as CMOS image sensors.
The LDOs feature a high power-supply rejection ratio (PSRR) of
75dB at 1kHz to deliver stable output voltages for sensitive loads
from an input voltage of between 1.7V to 5.25V. Output noise is
just 60μVrms between 10Hz and 100kHz for a fixed-output voltage of
between 1.1V to 3.3V (AP7315Q) or 0.9V to 3.6V (AP7343Q).
Both regulators are supplied in the SOT25 package.
