Automotive Compliant Linear Regulators from Diodes Incorporated Deliver High PSRR and Low Quiescent Current

ioPlano, Texas – October 9, 2019 – 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.
Both regulators are supplied in the SOT25 package. The AP7315Q/DQ parts are priced at $0.09 each and the AP7343Q/DQ at $0.14 each in 1000 piece quantities.

TE Connectivity Announced Ultra Small Spring Fingers

TE Connectivity (TE)’snew ultra small spring fingers have one of the smallest footprints in the market to save valuable PCB space, allowing for use in a broad range of applications with space constraints across various industries.TE’s ultra small spring fingerscan save valuable PCB space with one of the smallest footprints in the market. Closed-loop contact design ensures reliable connection to the PCB, better normal force and higher current capacity (1.5A). Robust side wall minimizes over- compression. Special anti-lifting design can improve assembly e ciency by locking the tip of the contact within the sidewall of the spring  nger, which helps prevent the contact from getting caught on an operator’s glove during assembly. Pick-and-place area supports auto-assembly processes. It also offered in different heights and styles.As an authorized distributor for TE Connectivity, Heilind Asia provides TE’s products and also value added services. Heilind Asia supports both original equipment …
