Top Alternatives to Infineon BCR401 & Slkor SL401 LDO Voltage Regulators

Slkor offers alternative replacement - BCR401 - for Infineon BCR401 42V, 10mA Low Dropout Voltage Regulator

VDD(V): 42V
IO(A): 65mA
IDDq(A): 160μA
TA(℃): 150℃
Package: SOT-23-6



Description

SL401 is a constant current driver chip with a default output current of 10mA. By using a bias resistor, the maximum output current can be set to 65mA, which can be used to drive low-power LEDs(The specific circuit can refer to Figure 6-1) At the same time, a transistor can also be connected to the output pin of SL401, and the SL401 feedback control function can be used to achieve dimming control of high-power LEDs above 65mA(The specific circuit can refer to Figure 6-2)


Features

● The output current is determined by the bias resistance and does not change with the number of LED lights in series or the change in the forward conduction voltage of the LED lights. 

● The output current is stable and will not change due to changes in the power supply voltage. It can be ignored that if the power line is too long, it will reduce the power supply voltage of SL401.


Application
● Switching mode power supplies

● DC-to-DC converters

● Motor Control, solar power

 Slkor LM393: A Cost-Effective Alternative to TI LM393DR and ONSEMI LM393DR2G V cc ：±18~36V V IO ：±3mV I IB ：25nA V I ：-0.3~36V T RE ：1.3μs Package：SOP-8 Description LM393 is an integrated circuit comprising two independent, high-precision voltage comparators, characterized by low offset voltage, with a maximum of 2.0mV. It is designed to operate over a wide voltage range with single-supply voltage, though it can also function with dual-supply voltage configurations. Moreover, it maintains low power consumption regardless of the supply voltage magnitude. One of its distinctive features is its ability to operate with a single-supply voltage, with the common-mode input voltage range of the comparators approaching ground level. The main applications of the LM393 include limiters, simple analog-to-digital converters, pulse generators, square wave generators, delay generators, wideband voltage-controlled oscillators, MOS clock timers, multi-frequency oscillators, and high-level digital ...

【SLKOR semiconductor】Protecting Automotive Electronics: SLKOR's SLESD5311N-2TR TVS Diode in Focus

图片
 Introduction   With the rapid advancement of technology, automobiles are making significant strides toward intelligence and connectivity. Modern in-car systems integrate numerous electronic devices such as entertainment systems, navigation systems, and autonomous driving sensors, all of which demand high voltage stability. However, during vehicle operation, various transient overvoltage threats may occur, such as those caused by engine ignition, lightning induction, and power switching. These overvoltage pulses can severely damage onboard electronics, causing system failures and negatively affecting driving safety and the overall driving experience. The transient voltage suppression  diode  ( TVS ) is an efficient overvoltage protection device that quickly responds to transient overvoltage events, clamping the voltage to a safe level and protecting automotive electronics from damage. The SL ESD 5311N-2TR, as a high-performance  TVS   diode , has broad...
