Web21 de mar. de 2024 · The usual solution to increase linear regulator current is to use an external pass transistor. These kind of circuits are described in regulator datasheet. … WebAs can be seen in equation 1, if you have a large voltage differential (Vin – Vout) across the regulator, and/or a high load current, then your regulator will dissipate high amounts of power. For instance, if the input is 12 V and the output is 3.3 V, the voltage differential would be calculated as 12 V – 3.3 V = 8.7 V.

WebThe image shows a simple shunt voltage regulator that operates by way of the Zener diode's action of maintaining a constant voltage across itself when the current through it is sufficient to take it into the Zener breakdown region. The resistor R 1 supplies the Zener current as well as the load current I R2 (R 2 is the load). R 1 can be calculated as = +, … Webthe regulator. Region 3 is above the unity-gain frequency, where the feedback loop has very little effect, so the out-put capacitor dominates along with any parasitics from V IN to V OUT. The gate driver’s ability to drive the pass-FET gate at high frequencies also has an effect in Region 3. A larger output capacitor with less equivalent ...
