General Description
AP1084 is a low dropout positive adjustable or fixed-mode
regulator with 5.0A output current capability. The product is
specifically designed to provide well-regulated supply for low
voltage IC applications such as high-speed bus termination and
low current 3.3V logic supply. AP1084 is also well suited for other
applications such as VGA cards. AP1084 is guaranteed to have
lower than 1.4V dropout at full load current making it ideal to
provide well-regulated outputs of 1.25 to 3.3V with 4.7 to
12V input supply.

Description
Adjustable (Ground only for fixed mode)
A resistor divider from this pin to the V
OUT
pin and ground sets the output voltage
(Ground only for Fixed-Mode).
The output of the regulator. A minimum of 10uF (0.15Ω ≤ ESR ≤ 20Ω) capacitor must
be connected from this pin to ground to insure stability.
The input pin of regulator. Typically a large storage capacitor is connected from this
pin to ground to insure that the input voltage does not sag below the minimum
dropout voltage during the load transient response. This pin must always be 1.4V
(1.3V) higher than V
OUT
in order for the device to regulate properly.

Notes:
3. See thermal regulation specifications for changes in output voltage due to heating effects. Line and load regulation are measured at a constant
junction temperature by low duty cycle pulse testing. Load regulation is measured at the output lead = 1/18” from the package.
4. Line and load regulation are guaranteed up to the maximum power dissipation of 15W. Power dissipation is determined by the difference
between input and output and the output current. Guaranteed maximum power dissipation will not be available over the full input/output range.
5. Test conditions for TO220-3L, TO252-3L and TO263-3L: Devices mounted on FR-4 substrate, single sided PC board, 2oz copper, with minimum
recommended pay layout, no air flow. The case point of θ
JC
is located on the thermal tab.

电饭锅提前跳开关的原因浅析
本帖最后由jameswangsynnex于2015-3-319:57编辑电饭锅在饭没煮熟之前,磁性开关跳到保温状态,这是电饭锅的常见通病,其主要原因有以下三点:一、磁钢失磁,这是使用年久的电饭锅易出现的故障。此外,市场上电饭锅质量良莠不齐,磁性开关不良更是多见。二、内锅底部变形或有污垢,导致与发热盘接触不良,使导热面减小热阻增大,造成提前跳开关。而内锅底变形主要是盛饭或清洗过程中用力过度,加之把内锅放在燃气灶或煤炉上烧饭所致。对此,可用木柄敲击,把内锅底调整与发热盘相吻合(发热盘变...
