    Roberts RD60 DB radio. Looking for some help Identify Component IC

    Hello. Im strugling to find a component.
    It is a DB radio, Input Voltage is 7.5v 800mA.

    The Component in question is 5 pin Sot-23 labeled as L1AH

    It takes 7.7 Vin then sends 5.5V to the gate of 358 transistor/MOSFET ic.

    358 takes 7.7v and outputs 5.5v same as gate Volage. NOTE if radio is off
    Gate pin is 7.7Voltage but transistor does not output any voltage.

    I have made schematics to best of my abilities, but im horrible at it the only Real Values are Voltages. and resistors.
    Appreciate any help.
    There should be images....

    This is a website with a reasonable amount of schematics.
    http://teleservis.com.ua/index.php?newsid=100
    Just wondering if any of them matches my schematics.

          clock radio / radio lifespan?
          by shelby5041
          hi
          ive got a modern digital clock radio approx 15yrs old

          my question is how long can a clock radio or a simple radio last ss farcas operating hours?

          since elec components have limited hour lifecspan i would imagine the radio or clock radio would eventually fail.

          the reason i ask is because i have my clock radio on radio function 24/7 for the past 7 years and its still working fine....i leave the radio on ..never turn off past 7years...thats approx 60000 hours

          it uses very little power just a few watts i would imagine that may have something...

          Schematic vs. Reality: Where Are the Resistors on My Sharp Clock Radio? Model FY-70CH
          by TinkerTron
          Hey everyone,

          I'm currently working on a mid-70s Sharp Electronic Digital Clock Radio, Model FY-70CH. I found the service manual online, printed it out, and have been studying it for a while. My main reasons for tackling this are: (1) I want to learn electronics and figured I'd start with something I had on hand, and (2) I want to fix its issues. Right now, the radio sounds awful, has about 5V DC at the speaker terminals, and the alarm time setting doesn't work. But I'm not asking how to fix these problems.

          Instead, here's what's been bugging me so far:
          The schematic...
