An LDO regulator doesn''t regulate if the voltage drops below the (output voltage + dropout voltage) which is guaranteed to happen with a LiPo battery. A better option is an up/down switching regulator, which will maintain a constant output voltage over a very wide range of input voltages above and below the output voltage. Pololu

Customer ServiceVoltage regulators are an essential part of most electronic hardware products. The function of a voltage regulator is to provide a stable voltage on the output of the regulator while the input voltage can be variable. Regulators (as well as battery chargers) can be broadly classified as linear or switching. Since linear regulators are much easier understand we''ll start with them,
Customer ServiceI''m currently working on a project in which the components must be powered by a 3.3v source. I want to use a 3.7V rechargeable lithium polymer battery and a voltage regulator to do this. Looking at various sources for electrical components online, the number of different voltage regulators with a 3.3V output is massive. There are also many different attributes for
Customer ServiceA linear regulator (Figure 1a) converts battery voltage to a logic supply, and one or more switchers generate other voltages required for analog circuitry and liquid-crystal-display (LCD) bias. A different approach (Figure 1b) achieves noise and ripple rejection with a combination of linear and switch-mode regulators. Because power

Customer ServiceBattery powered projects (particularly those with periodic events spaced quite a bit apart) usually benefit from using a linear regulator. Looking at your requirements (LiPo 4.2V to Vo + dropout voltage) a linear regulator will be (on average 3.7V battery, regulated output 3.0V) 81% efficient which is close to the SMPS solution anyway.
Customer ServiceFor example, if you''re input supply is 3.6 V (voltage of a lithium polymer battery) and you are outputting 3.3 V, then a linear regulator will have a power efficiency of 3.3 V / 3.6 V = 91.7%. Step-up voltage regulators
Customer ServiceThe STEVAL-ISB032V1 is a product evaluation board based on the STNS01, which is a linear charger for single cell Li-Ion batteries integrating an LDO regulator and several battery protection functions.

Customer ServiceIn theory, a linear battery charger with a sepa-rate power path for the system is a fairly simple design concept and can be built with an LDO adjusted to 4.2 V; a current-limit resistor; three p-channel FETs to switch the system load between the input power and the battery source; and some bias parts.
Customer ServiceYour motorcycle probably came from the factory with a normal lead or gel battery (check your manual). That said, a lithium battery is super nice to have since it is small, strong and lightweight! However, if your regulator and rectifier are outdated, they can overload the lithium battery which can lead to overheating or even an explosion.
